51: Chapter 1. General Installation Considerations
52:
53: Before starting the installation, first you need to know what do you
54: want to use PHP for. There are three main fields you can use PHP, as
55: described in the What can PHP do? section:
56:
57: * Websites and web applications (server-side scripting)
58: * Command line scripting
59: * Desktop (GUI) applications
60:
61: For the first and most common form, you need three things: PHP itself,
62: a web server and a web browser. You probably already have a web
63: browser, and depending on your operating system setup, you may also
64: have a web server (e.g. Apache on Linux and MacOS X; IIS on Windows).
65: You may also rent webspace at a company. This way, you don't need to
66: set up anything on your own, only write your PHP scripts, upload it to
67: the server you rent, and see the results in your browser.
68:
69: In case of setting up the server and PHP on your own, you have two
70: choices for the method of connecting PHP to the server. For many
71: servers PHP has a direct module interface (also called SAPI). These
72: servers include Apache, Microsoft Internet Information Server, Netscape
73: and iPlanet servers. Many other servers have support for ISAPI, the
74: Microsoft module interface (OmniHTTPd for example). If PHP has no
75: module support for your web server, you can always use it as a CGI or
76: FastCGI processor. This means you set up your server to use the CGI
77: executable of PHP to process all PHP file requests on the server.
78:
79: If you are also interested to use PHP for command line scripting (e.g.
80: write scripts autogenerating some images for you offline, or processing
81: text files depending on some arguments you pass to them), you always
82: need the command line executable. For more information, read the
83: section about writing command line PHP applications. In this case, you
84: need no server and no browser.
85:
86: With PHP you can also write desktop GUI applications using the PHP-GTK
87: extension. This is a completely different approach than writing web
88: pages, as you do not output any HTML, but manage Windows and objects
89: within them. For more information about PHP-GTK, please visit the site
90: dedicated to this extension. PHP-GTK is not included in the official
91: PHP distribution.
92:
93: From now on, this section deals with setting up PHP for web servers on
94: Unix and Windows with server module interfaces and CGI executables. You
95: will also find information on the command line executable in the
96: following sections.
97:
98: PHP source code and binary distributions for Windows can be found at
99: http://www.php.net/downloads.php. We recommend you to choose a mirror
100: nearest to you for downloading the distributions.
101: __________________________________________________________________
102:
103: Chapter 2. Installation on Windows systems
104:
105: This section applies to Windows 98/Me and Windows NT/2000/XP/2003. PHP
106: will not work on 16 bit platforms such as Windows 3.1 and sometimes we
107: refer to the supported Windows platforms as Win32. Windows 95 is no
108: longer supported as of PHP 4.3.0.
109:
110: There are two main ways to install PHP for Windows: either manually or
111: by using the installer.
112:
113: If you have Microsoft Visual Studio, you can also build PHP from the
114: original source code.
115:
116: Once you have PHP installed on your Windows system, you may also want
117: to load various extensions for added functionality.
118:
119: Warning
120:
121: There are several all-in-one installers over the Internet, but none of
122: those are endorsed by PHP.net, as we believe that the manual
123: installation is the best choice to have your system secure and
124: optimised.
125: __________________________________________________________________
126:
127: Windows Installer (PHP 5.2 and later)
128:
129: The Windows PHP installer for later versions of PHP is built using MSI
130: technology using the Wix Toolkit (http://wix.sourceforge.net/). It will
131: install and configure PHP and all the built-in and PECL extensions, as
132: well as configure many of the popular web servers such as IIS, Apache,
133: and Xitami.
134:
135: First, install your selected HTTP (web) server on your system, and make
136: sure that it works. Then proceed with one of the following install
137: types.
138: __________________________________________________________________
139:
140: Normal Install
141:
142: Run the MSI installer and follow the instructions provided by the
143: installation wizard. You will be prompted to select the Web Server you
144: wish to configure first, along with any configuration details needed.
145:
146: You will then be prompted to select which features and extensions you
147: wish to install and enable. By selecting "Will be installed on local
148: hard drive" in the drop-down menu for each item you can trigger whether
149: to install the feature or not. By selecting "Entire feature will be
150: installed on local hard drive", you will be able to install all
151: sub-features of the included feature ( for example by selecting this
152: options for the feature "PDO" you will install all PDO Drivers ).
153:
154: Warning
155:
156: It is not recommended to install all extensions by default, since many
157: other them require dependencies from outside PHP in order to function
158: properly. Instead, use the Installation Repair Mode that can be
159: triggered thru the 'Add/Remove Programs' control panel to enable or
160: disable extensions and features after installation.
161:
162: The installer then sets up PHP to be used in Windows and the php.ini
163: file, and configures certain web servers to use PHP. The installer will
164: currently configure IIS (CGI mode only), Apache, Xitami, and Sambar
165: Server; if you are using a different web server you'll need to
166: configure it manually.
167: __________________________________________________________________
168:
169: Silent Install
170:
171: The installer also supports a silent mode, which is helpful for Systems
172: Administrators to deploy PHP easily. To use silent mode:
173: msiexec.exe /i php-VERSION-win32-install.msi /q
174:
175: You can control the install directory by passing it as a parameter to
176: the install. For example, to install to e:\php:
177: msiexec.exe /i php-VERSION-win32-install.msi /q INSTALLDIR=e:\php
178:
179: You can also use the same syntax to specify the Apache Configuration
180: Directory (APACHEDIR), the Sambar Server directory (SAMBARDIR), and the
181: Xitami Server directory (XITAMIDIR).
182:
183: You can also specify what features to install. For example, to install
184: the mysqli extension and the CGI executable:
185: msiexec.exe /i php-VERSION-win32-install.msi /q ADDLOCAL=cgi,ext_php_mysqli
186:
187: The current list of Features to install is as follows:
188: MainExecutable - php.exe executable
189: ScriptExecutable - php-win.exe executable
190: ext_php_* - the various extensions ( for example: ext_php_mysql for MySQL )
191: apache13 - Apache 1.3 module
192: apache20 - Apache 2.0 module
193: apache22 - Apache 2,2 module
194: apacheCGI - Apache CGI executable
195: iis4ISAPI - IIS ISAPI module
196: iis4CGI - IIS CGI executable
197: NSAPI - Sun/iPlanet/Netscape server module
198: Xitami - Xitami CGI executable
199: Sambar - Sambar Server ISAPI module
200: CGI - php-cgi.exe executable
201: PEAR - PEAR installer
202: Manual - PHP Manual in CHM Format

210: Windows Installer (PHP 5.1.0 and earlier)
211:
212: The Windows PHP installer is available from the downloads page at
213: http://www.php.net/downloads.php. This installs the CGI version of PHP
214: and for IIS, PWS, and Xitami, it configures the web server as well. The
215: installer does not include any extra external PHP extensions
216: (php_*.dll) as you'll only find those in the Windows Zip Package and
217: PECL downloads.
218:
219: Note: While the Windows installer is an easy way to make PHP work,
220: it is restricted in many aspects as, for example, the automatic
221: setup of extensions is not supported. Use of the installer isn't the
222: preferred method for installing PHP.
223:
224: First, install your selected HTTP (web) server on your system, and make
225: sure that it works.
226:
227: Run the executable installer and follow the instructions provided by
228: the installation wizard. Two types of installation are supported -
229: standard, which provides sensible defaults for all the settings it can,
230: and advanced, which asks questions as it goes along.
231:
232: The installation wizard gathers enough information to set up the
233: php.ini file, and configure certain web servers to use PHP. One of the
234: web servers the PHP installer does not configure for is Apache, so
235: you'll need to configure it manually.
236:
237: Once the installation has completed, the installer will inform you if
238: you need to restart your system, restart the server, or just start
239: using PHP.
240:
241: Warning
242:
243: Be aware, that this setup of PHP is not secure. If you would like to
244: have a secure PHP setup, you'd better go on the manual way, and set
245: every option carefully. This automatically working setup gives you an
246: instantly working PHP installation, but it is not meant to be used on
247: online servers.
248: __________________________________________________________________
249:
250: Manual Installation Steps
251:
252: This install guide will help you manually install and configure PHP
253: with a web server on Microsoft Windows. To get started you'll need to
254: download the zip binary distribution from the downloads page at
255: http://www.php.net/downloads.php.
256:
257: Although there are many all-in-one installation kits, and we also
258: distribute a PHP installer for Microsoft Windows, we recommend you take
259: the time to setup PHP yourself as this will provide you with a better
260: understanding of the system, and enables you to install PHP extensions
261: easily when needed.
262:
263: Upgrading from a previous PHP version: Previous editions of the
264: manual suggest moving various ini and DLL files into your SYSTEM
265: (i.e. C:\WINDOWS) folder and while this simplifies the installation
266: procedure it makes upgrading difficult. We advise you remove all of
267: these files (like php.ini and PHP related DLLs from the Windows
268: SYSTEM folder) before moving on with a new PHP installation. Be sure
269: to backup these files as you might break the entire system. The old
270: php.ini might be useful in setting up the new PHP as well. And as
271: you'll soon learn, the preferred method for installing PHP is to
272: keep all PHP related files in one directory and have this directory
273: available to your systems PATH.
274:
275: MDAC requirements: If you use Microsoft Windows 98/NT4 download the
276: latest version of the Microsoft Data Access Components (MDAC) for
277: your platform. MDAC is available at http://msdn.microsoft.com/data/.
278: This requirement exists because ODBC is built into the distributed
279: Windows binaries.
280:
281: The following steps should be completed on all installations before any
282: server specific instructions are performed:
283:
284: Extract the distribution file into a directory of your choice. If you
285: are installing PHP 4, extract to C:\, as the zip file expands to a
286: foldername like php-4.3.7-Win32. If you are installing PHP 5, extract
287: to C:\php as the zip file doesn't expand as in PHP 4. You may choose a
288: different location but do not have spaces in the path (like C:\Program
289: Files\PHP) as some web servers will crash if you do.
290:
291: The directory structure extracted from the zip is different for PHP
292: versions 4 and 5 and look like as follows:
293:
294: Example 2-2. PHP 5 package structure
295: c:\php

347: |
348: |-php5ts.dll -- core PHP DLL
349: |
350: |-...
351:
352: Notice the differences and similarities. Both PHP 4 and PHP 5 have a
353: CGI executable, a CLI executable, and server modules, but they are
354: located in different folders and/or have different names. While PHP 4
355: packages have the server modules in the sapi folder, PHP 5
356: distributions have no such directory and instead they're in the PHP
357: folder root. The supporting DLLs for the PHP 5 extensions are also not
358: in a separate directory.
359:
360: Note: In PHP 4, you should move all files located in the dll and
361: sapi folders to the main folder (e.g. C:\php).
362:
363: Here is a list of server modules shipped with PHP 5:
364:
365: * sapi/php5apache2_2.dll - Apache 2.2.x module.
366: * sapi/php5apache.dll (php5apache.dll) - Apache 1.x module
367: * sapi/php5apache2.dll (php5apache2.dll) - - Apache 2.0.x module.
368: * sapi/php5isapi.dll - ISAPI Module for ISAPI compliant web servers
369: like IIS 5.0 or newer. However the FCGI SAPI is recommended with
370: IIS
371: * sapi/php5nsapi.dll (php5nsapi.dll) - Sun/iPlanet/Netscape server
372: module.
373:
374: Server modules provide significantly better performance and additional
375: functionality compared to the CGI binary. The FastCGI is significantly
376: more stable and can be faster than the ISAPI module with IIS.
377: The CLI version is designed to let you use PHP for command line
378: scripting. More information about CLI is available in the chapter
379: about using PHP from the command line.
380:
381: Warning
382:
383: The SAPI modules have been significantly improved as of the 4.1
384: release, however, in older systems you may encounter server errors or
385: other server modules failing, such as ASP.
386:
387: The CGI and CLI binaries, and the web server modules all require the
388: php5ts.dll file to be available to them. You have to make
389: sure that this file can be found by your PHP installation. The search
390: order for this DLL is as follows:
391:
392: * The same directory from where php.exe is called, or in case you use
393: a SAPI module, the web server's directory (e.g. C:\Program
394: Files\Apache Group\Apache2\bin).
395: * Any directory in your Windows PATH environment variable.
396:
397: To make php5ts.dll available you have three options: copy
398: the file to the Windows system directory, copy the file to the web
399: server's directory, or add your PHP directory, C:\php to the PATH. For
400: better maintenance, we advise you to follow the last option, add C:\php
401: to the PATH, because it will be simpler to upgrade PHP in the future.
402: Read more about how to add your PHP directory to PATH in the
403: corresponding FAQ entry (and then don't forget to restart the computer
404: - logoff isn't enough).
405:
406: The next step is to set up a valid configuration file for PHP, php.ini.
407: There are two ini files distributed in the zip file, php.ini-development
408: and php.ini-production. We advise you to use php.ini-production,
409: because we optimized the default settings in this file for performance,
410: and security. Read this well documented file carefully because it has
411: changes from php.ini-production that will drastically affect your setup.
412: Some examples are display_errors being off and magic_quotes_gpc being off.
413: In addition to reading these, study the ini settings and set every
414: element manually yourself. If you would like to achieve the best
415: security, then this is the way for you, although PHP works fine with
416: these default ini files. Copy your chosen ini-file to a directory that
417: PHP is able to find and rename it to php.ini. PHP searches for php.ini
418: in the locations described in the Section called The configuration file
419: in Chapter 5 section.
420:
421: If you are running Apache 2, the simpler option is to use the PHPIniDir
422: directive (read the installation on Apache 2 page), otherwise your best
423: option is to set the PHPRC environment variable. This process is
424: explained in the following FAQ entry.
425:
426: Note: If you're using NTFS on Windows NT, 2000, XP or 2003, make
427: sure that the user running the web server has read permissions to
428: your php.ini (e.g. make it readable by Everyone).
429:
430: The following steps are optional:
431:
432: * Edit your new php.ini file. If you plan to use OmniHTTPd, do not
433: follow the next step. Set the doc_root to point to your web servers
434: document_root. For example:
435:
436: doc_root = c:\inetpub\wwwroot // for IIS/PWS
437:
438: doc_root = c:\apache\htdocs // for Apache
439:
440: * Choose the extensions you would like to load when PHP starts. See
441: the section about Windows extensions, about how to set up one, and
442: what is already built in. Note that on a new installation it is
443: advisable to first get PHP working and tested without any
444: extensions before enabling them in php.ini.
445: * On PWS and IIS, you can set the browscap configuration setting to
446: point to: c:\windows\system\inetsrv\browscap.ini on Windows 9x/Me,
447: c:\winnt\system32\inetsrv\browscap.ini on NT/2000, and
448: c:\windows\system32\inetsrv\browscap.ini on XP. For an up-to-date
449: browscap.ini, read the following FAQ.
450:
451: PHP is now setup on your system. The next step is to choose a web
452: server, and enable it to run PHP. Choose a web server from the table of
453: contents.
454: __________________________________________________________________
455:
456: ActiveScript
457:
458: This section contains notes specific to the ActiveScript installation.
459:
460: ActiveScript is a Windows only SAPI that enables you to use PHP script
461: in any ActiveScript compliant host, like Windows Script Host,
462: ASP/ASP.NET, Windows Script Components or Microsoft Scriptlet control.
463:
464: As of PHP 5.0.1, ActiveScript has been moved to the PECL repository.
465: The DLL for this PECL extension may be downloaded from either the PHP
466: Downloads page or from http://pecl4win.php.net/
467:
468: Note: You should read the manual installation steps first!
469:
470: After installing PHP, you should download the ActiveScript DLL
471: (php5activescript.dll) and place it in the main PHP folder (e.g.
472: C:\php).
473:
474: After having all the files needed, you must register the DLL on your
475: system. To achieve this, open a Command Prompt window (located in the
476: Start Menu). Then go to your PHP directory by typing something like cd
477: C:\php. To register the DLL just type regsvr32 php5activescript.dll.
478:
479: To test if ActiveScript is working, create a new file, named test.wsf
480: (the extension is very important) and type:
481: <job id="test">
482:
483: <script language="PHPScript">
484: $WScript->Echo("Hello World!");
485: </script>
486:
487: </job>
488:
489: Save and double-click on the file. If you receive a little window
490: saying "Hello World!" you're done.
491:
492: Note: In PHP 4, the engine was named 'ActivePHP', so if you are
493: using PHP 4, you should replace 'PHPScript' with 'ActivePHP' in the
494: above example.
495:
496: Note: ActiveScript doesn't use the default php.ini file. Instead, it
497: will look only in the same directory as the .exe that caused it to
498: load. You should create php-activescript.ini and place it in that
499: folder, if you wish to load extensions, etc.
500: __________________________________________________________________
501:
502: Microsoft IIS / PWS
503:
504: This section contains notes and hints specific to IIS (Microsoft
505: Internet Information Server).
506:
507: Warning
508:
509: By using the CGI setup, your server is open to several possible
510: attacks. Please read our CGI security section to learn how to defend
511: yourself from those attacks.
512: __________________________________________________________________
513:
514: General considerations for all installations of PHP with IIS or PWS
515:
516: * First, read the Manual Installation Instructions. Do not skip this
517: step as it provides crucial information for installing PHP on
518: Windows.
519: * CGI users must set the cgi.force_redirect PHP directive to 0 inside
520: php.ini. Read the faq on cgi.force_redirect for important details.
521: Also, CGI users may want to set the cgi.redirect_status_env
522: directive. When using directives, be sure these directives aren't
523: commented out inside php.ini.
524: * The PHP 4 CGI is named php.exe while in PHP 5 it's php-cgi.exe. In
525: PHP 5, php.exe is the CLI, and not the CGI.
526: * Modify the Windows PATH environment variable to include the PHP
527: directory. This way the PHP DLL files and PHP executables can all
528: remain in the PHP directory without cluttering up the Windows
529: system directory. For more details, see the FAQ on Setting the
530: PATH.
531: * The IIS user (usually IUSR_MACHINENAME) needs permission to read
532: various files and directories, such as php.ini, docroot, and the
533: session tmp directory.
534: * Be sure the extension_dir and doc_root PHP directives are
535: appropriately set in php.ini. These directives depend on the system
536: that PHP is being installed on. In PHP 4, the extension_dir is
537: extensions while with PHP 5 it's ext. So, an example PHP 5
538: extensions_dir value is "c:\php\ext" and an example IIS doc_root
539: value is "c:\Inetpub\wwwroot".
540: * PHP extension DLL files, such as php_mysql.dll and php_curl.dll,
541: are found in the zip package of the PHP download (not the PHP
542: installer). In PHP 5, many extensions are part of PECL and can be
543: downloaded in the "Collection of PECL modules" package. Files such
544: as php_zip.dll and php_ssh2.dll. Download PHP files here.
545: * When defining the executable, the 'check that file exists' box may
546: also be checked. For a small performance penalty, the IIS (or PWS)
547: will check that the script file exists and sort out authentication
548: before firing up PHP. This means that the web server will provide
549: sensible 404 style error messages instead of CGI errors complaining
550: that PHP did not output any data.
551: __________________________________________________________________
552:
553: Windows NT/200x/XP and IIS 4 or newer
554:
555: PHP may be installed as a CGI binary, or with the ISAPI module. In
556: either case, you need to start the Microsoft Management Console (may
557: appear as 'Internet Services Manager', either in your Windows NT 4.0
558: Option Pack branch or the Control Panel=>Administrative Tools under
559: Windows 2000/XP). Then right click on your Web server node (this will
560: most probably appear as 'Default Web Server'), and select 'Properties'.
561:
562: If you want to use the CGI binary, do the following:
563:
564: * Under 'Home Directory', 'Virtual Directory', or 'Directory', do the
565: following:
566: * Change the Execute Permissions to 'Scripts only'
567: * Click on the 'Configuration' button, and choose the Application
568: Mappings tab. Click Add and set the Executable path to the
569: appropriate CGI file. An example PHP 5 value is: C:\php\php-cgi.exe
570: Supply .php as the extension. Leave 'Method exclusions' blank, and
571: check the 'Script engine' checkbox. Now, click OK a few times.
572: * Set up the appropriate security. (This is done in Internet Service
573: Manager), and if your NT Server uses NTFS file system, add execute
574: rights for I_USR_ to the directory that contains php.exe /
575: php-cgi.exe.
576:
577: To use the ISAPI module, do the following:
578:
579: * If you don't want to perform HTTP Authentication using PHP, you can
580: (and should) skip this step. Under ISAPI Filters, add a new ISAPI
581: filter. Use PHP as the filter name, and supply a path to the
582: php5isapi.dll.
583: * Under 'Home Directory', 'Virtual Directory', or 'Directory', do the
584: following:
585: * Change the Execute Permissions to 'Scripts only'
586: * Click on the 'Configuration' button, and choose the Application
587: Mappings tab. Click Add and set the Executable path to the
588: appropriate ISAPI DLL. An example PHP 5 value is:
589: C:\php\php5isapi.dll Supply .php as the extension. Leave 'Method
590: exclusions' blank, and check the 'Script engine' checkbox. Now,
591: click OK a few times.
592: * Stop IIS completely (NET STOP iisadmin)
593: * Start IIS again (NET START w3svc)
594:
595: With IIS 6 (2003 Server), open up the IIS Manager, go to Web Service
596: Extensions, choose "Add a new Web service extension", enter in a name
597: such as PHP, choose the Add button and for the value browse to either
598: the ISAPI file (php5isapi.dll) or CGI (php.exe or
599: php-cgi.exe) then check "Set extension status to Allowed" and click OK.
600:
601: In order to use index.php as a default content page, do the following:
602: From within the Documents tab, choose Add. Type in index.php and click
603: OK. Adjust the order by choosing Move Up or Move Down. This is similar
604: to setting DirectoryIndex with Apache.
605:
606: The steps above must be repeated for each extension that is to be
607: associated with PHP scripts. .php is the most common although .php3 may
608: be required for legacy applications.
609:
610: If you experience 100% CPU usage after some time, turn off the IIS
611: setting Cache ISAPI Application.

619: Apache 1.3.x on Microsoft Windows
620:
621: This section contains notes and hints specific to Apache 1.3.x installs
622: of PHP on Microsoft Windows systems. There are also instructions and
623: notes for Apache 2 on a separate page.
624:
625: Note: Please read the manual installation steps first!
626:
627: There are two ways to set up PHP to work with Apache 1.3.x on Windows.
628: One is to use the CGI binary (php.exe for PHP 4 and php-cgi.exe for PHP
629: 5), the other is to use the Apache Module DLL. In either case you need
630: to edit your httpd.conf to configure Apache to work with PHP, and then
631: restart the server.
632:
633: It is worth noting here that now the SAPI module has been made more
634: stable under Windows, we recommend it's use above the CGI binary, since
635: it is more transparent and secure.
636:
637: Although there can be a few variations of configuring PHP under Apache,
638: these are simple enough to be used by the newcomer. Please consult the
639: Apache Documentation for further configuration directives.
640:
641: After changing the configuration file, remember to restart the server,
642: for example, NET STOP APACHE followed by NET START APACHE, if you run
643: Apache as a Windows Service, or use your regular shortcuts.
644:
645: Note: Remember that when adding path values in the Apache
646: configuration files on Windows, all backslashes such as
647: c:\directory\file.ext must be converted to forward slashes, as
648: c:/directory/file.ext. A trailing slash may also be necessary for
649: directories.
650: __________________________________________________________________
651:
652: Installing as an Apache module
653:
654: You should add the following lines to your Apache httpd.conf file:
655:
656: Example 2-3. PHP as an Apache 1.3.x module
657:
658: This assumes PHP is installed to c:\php. Adjust the path if this is not
659: the case.
660:
661: For PHP 5:
662: # Add to the end of the LoadModule section
663: LoadModule php5_module "C:/php/php5apache.dll"
664:
665: # Add to the end of the AddModule section
666: AddModule mod_php5.c
667:
668: For both:
669: # Add this line inside the <IfModule mod_mime.c> conditional brace
670: AddType application/x-httpd-php .php
671:
672: # For syntax highlighted .phps files, also add
673: AddType application/x-httpd-php-source .phps
674: __________________________________________________________________
675:
676: Installing as a CGI binary
677:
678: If you unzipped the PHP package to C:\php\ as described in the Manual
679: Installation Steps section, you need to insert these lines to your
680: Apache configuration file to set up the CGI binary:
681:
682: Example 2-4. PHP and Apache 1.3.x as CGI
683: ScriptAlias /php/ "c:/php/"
684: AddType application/x-httpd-php .php
685:
686: # For PHP 4
687: Action application/x-httpd-php "/php/php.exe"
688:
689: # For PHP 5
690: Action application/x-httpd-php "/php/php-cgi.exe"
691:
692: # specify the directory where php.ini is
693: SetEnv PHPRC C:/php
694:
695: Note that the second line in the list above can be found in the actual
696: versions of httpd.conf, but it is commented out. Remember also to
697: substitute the c:/php/ for your actual path to PHP.
698:
699: Warning
700:
701: By using the CGI setup, your server is open to several possible
702: attacks. Please read our CGI security section to learn how to defend
703: yourself from those attacks.
704:
705: If you would like to present PHP source files syntax highlighted, there
706: is no such convenient option as with the module version of PHP. If you
707: chose to configure Apache to use PHP as a CGI binary, you will need to
708: use the highlight_file() function. To do this simply create a PHP
709: script file and add this code: <?php
710: highlight_file('some_php_script.php'); ?>.
711: __________________________________________________________________
712:
713: Apache 2.0.x on Microsoft Windows
714:
715: This section contains notes and hints specific to Apache 2.0.x installs
716: of PHP on Microsoft Windows systems. We also have instructions and
717: notes for Apache 1.3.x users on a separate page.
718:
719: Note: You should read the manual installation steps first!
720:
721: Apache 2.2.x Support: Users of Apache 2.2.x may use the
722: documentation below except the appropriate DLL file is named
723: php5apache2_2.dll and it only exists as of PHP 5.2.0. See also
724: http://snaps.php.net/
725:
726: Warning
727:
728: We do not recommend using a threaded MPM in production with Apache2.
729: Use the prefork MPM instead, or use Apache1. For information on why,
730: read the related FAQ entry on using Apache2 with a threaded MPM
731:
732: You are highly encouraged to take a look at the Apache Documentation to
733: get a basic understanding of the Apache 2.0.x Server. Also consider to
734: read the Windows specific notes for Apache 2.0.x before reading on
735: here.
736:
737: PHP and Apache 2.0.x compatibility notes: The following versions of
738: PHP are known to work with the most recent version of Apache 2.0.x:
739:
740: * PHP 4.3.0 or later available at http://www.php.net/downloads.php.
741: * the latest stable development version. Get the source code
742: http://snaps.php.net/php5-latest.tar.gz or download binaries for
743: Windows http://snaps.php.net/win32/php5-win32-latest.zip.
744: * a prerelease version downloadable from http://qa.php.net/.
745: * you have always the option to obtain PHP through SVN.
746:
747: These versions of PHP are compatible to Apache 2.0.40 and later.
748:
749: Apache 2.0 SAPI-support started with PHP 4.2.0. PHP 4.2.3 works with
750: Apache 2.0.39, don't use any other version of Apache with PHP 4.2.3.
751: However, the recommended setup is to use PHP 4.3.0 or later with the
752: most recent version of Apache2.
753:
754: All mentioned versions of PHP will work still with Apache 1.3.x.
755:
756: Warning
757:
758: Apache 2.0.x is designed to run on Windows NT 4.0, Windows 2000 or
759: Windows XP. At this time, support for Windows 9x is incomplete. Apache
760: 2.0.x is not expected to work on those platforms at this time.
761:
762: Download the most recent version of Apache 2.0.x and a fitting PHP
763: version. Follow the Manual Installation Steps and come back to go on
764: with the integration of PHP and Apache.
765:
766: There are two ways to set up PHP to work with Apache 2.0.x on Windows.
767: One is to use the CGI binary the other is to use the Apache module DLL.
768: In either case you need to edit your httpd.conf to configure Apache to
769: work with PHP and then restart the server.
770:
771: Note: Remember that when adding path values in the Apache
772: configuration files on Windows, all backslashes such as
773: c:\directory\file.ext must be converted to forward slashes, as
774: c:/directory/file.ext. A trailing slash may also be necessary for
775: directories.
776: __________________________________________________________________
777:
778: Installing as a CGI binary
779:
780: You need to insert these three lines to your Apache httpd.conf
781: configuration file to set up the CGI binary:
782:
783: Example 2-5. PHP and Apache 2.0 as CGI
784: ScriptAlias /php/ "c:/php/"
785: AddType application/x-httpd-php .php
786:
787: # For PHP 4
788: Action application/x-httpd-php "/php/php.exe"
789:
790: # For PHP 5
791: Action application/x-httpd-php "/php/php-cgi.exe"
792:
793: Warning
794:
795: By using the CGI setup, your server is open to several possible
796: attacks. Please read our CGI security section to learn how to defend
797: yourself from those attacks.
798: __________________________________________________________________
799:
800: Installing as an Apache module
801:
802: You need to insert these two lines to your Apache httpd.conf
803: configuration file to set up the PHP module for Apache 2.0:
804:
805: Example 2-6. PHP and Apache 2.0 as Module
806:
807: # For PHP 5 do something like this:
808: LoadModule php5_module "c:/php/php5apache2.dll"
809: AddType application/x-httpd-php .php
810:
811: # configure the path to php.ini
812: PHPIniDir "C:/php"
813:
814: Note: Remember to substitute your actual path to PHP for the c:/php/
815: in the above examples. Take care to use either
816: php5apache2.dll in your LoadModule directive and not php5apache.dll
817: as the latter ones are designed to run with Apache 1.3.x.
818:
819: Note: If you want to use content negotiation, read related FAQ.
820:
821: Warning
822:
823: Don't mix up your installation with DLL files from different PHP
824: versions. You have the only choice to use the DLL's and extensions that
825: ship with your downloaded PHP version.

828: Sun, iPlanet and Netscape servers on Microsoft Windows
829:
830: This section contains notes and hints specific to Sun Java System Web
831: Server, Sun ONE Web Server, iPlanet and Netscape server installs of PHP
832: on Windows.
833:
834: From PHP 4.3.3 on you can use PHP scripts with the NSAPI module to
835: generate custom directory listings and error pages. Additional
836: functions for Apache compatibility are also available. For support in
837: current web servers read the note about subrequests.
838: __________________________________________________________________
839:
840: CGI setup on Sun, iPlanet and Netscape servers
841:
842: To install PHP as a CGI handler, do the following:
843:
844: * Copy php5ts.dll to your systemroot (the directory where you
845: installed Windows)
846: * Make a file association from the command line. Type the following
847: two lines:
848:
849: assoc .php=PHPScript
850: ftype PHPScript=c:\php\php.exe %1 %*
851:
852: * In the Netscape Enterprise Administration Server create a dummy
853: shellcgi directory and remove it just after (this step creates 5
854: important lines in obj.conf and allow the web server to handle
855: shellcgi scripts).
856: * In the Netscape Enterprise Administration Server create a new mime
857: type (Category: type, Content-Type: magnus-internal/shellcgi, File
858: Suffix:php).
859: * Do it for each web server instance you want PHP to run
860:
861: More details about setting up PHP as a CGI executable can be found
862: here: http://benoit.noss.free.fr/php/install-php.html
863: __________________________________________________________________
864:
865: NSAPI setup on Sun, iPlanet and Netscape servers
866:
867: To install PHP with NSAPI, do the following:
868:
869: * Copy php5ts.dll to your systemroot (the directory where you
870: installed Windows)
871: * Make a file association from the command line. Type the following
872: two lines:
873:
874: assoc .php=PHPScript
875: ftype PHPScript=c:\php\php.exe %1 %*
876:
877: * In the Netscape Enterprise Administration Server create a new mime
878: type (Category: type, Content-Type: magnus-internal/x-httpd-php,
879: File Suffix: php).
880: * Edit magnus.conf (for servers >= 6) or obj.conf (for servers < 6)
881: and add the following: You should place the lines after mime types
882: init.
883:
884: Init fn="load-modules" funcs="php5_init,php5_execute,php5_auth_trans" shlib="c:/
885: php/sapi/php5nsapi.dll"
886: Init fn="php5_init" LateInit="yes" errorString="Failed to initialise PHP!" [php_
887: ini="c:/path/to/php.ini"]
888:
889: The php_ini parameter is optional but with it you
890: can place your php.ini in your web server configuration directory.
891: * Configure the default object in obj.conf (for virtual server
892: classes [Sun Web Server 6.0+] in their vserver.obj.conf): In the
893: <Object name="default"> section, place this line necessarily after
894: all 'ObjectType' and before all 'AddLog' lines:
895:
896: Service fn="php5_execute" type="magnus-internal/x-httpd-php" [inikey=value inike
897: y=value ...]
898:
899: As additional parameters you can add some special
900: php.ini-values, for example you can set a
901: docroot="/path/to/docroot" specific to the context php5_execute is
902: called. For boolean ini-keys please use 0/1 as value, not
903: "On","Off",... (this will not work correctly), e.g.
904: zlib.output_compression=1 instead of zlib.output_compression="On"
905: * This is only needed if you want to configure a directory that only
906: consists of PHP scripts (same like a cgi-bin directory):
907:
908: <Object name="x-httpd-php">
909: ObjectType fn="force-type" type="magnus-internal/x-httpd-php"
910: Service fn=php5_execute [inikey=value inikey=value ...]
911: </Object>
912:
913: After that you can configure a directory in the Administration
914: server and assign it the style x-httpd-php. All files in it will
915: get executed as PHP. This is nice to hide PHP usage by renaming
916: files to .html.
917: * Restart your web service and apply changes
918: * Do it for each web server instance you want PHP to run
919:
920: Note: More details about setting up PHP as an NSAPI filter can be
921: found here: http://benoit.noss.free.fr/php/install-php4.html
922:
923: Note: The stacksize that PHP uses depends on the configuration of
924: the web server. If you get crashes with very large PHP scripts, it
925: is recommended to raise it with the Admin Server (in the section
926: "MAGNUS EDITOR").
927: __________________________________________________________________
928:
929: CGI environment and recommended modifications in php.ini
930:
931: Important when writing PHP scripts is the fact that Sun JSWS/Sun ONE
932: WS/iPlanet/Netscape is a multithreaded web server. Because of that all
933: requests are running in the same process space (the space of the web
934: server itself) and this space has only one environment. If you want to
935: get CGI variables like PATH_INFO, HTTP_HOST etc. it is not the correct
936: way to try this in the old PHP 3.x way with getenv() or a similar way
937: (register globals to environment, $_ENV). You would only get the
938: environment of the running web server without any valid CGI variables!
939:
940: Note: Why are there (invalid) CGI variables in the environment?
941:
942: Answer: This is because you started the web server process from the
943: admin server which runs the startup script of the web server, you
944: wanted to start, as a CGI script (a CGI script inside of the admin
945: server!). This is why the environment of the started web server has
946: some CGI environment variables in it. You can test this by starting
947: the web server not from the administration server. Use the command
948: line as root user and start it manually - you will see there are no
949: CGI-like environment variables.
950: __________________________________________________________________
951:
952: Special use for error pages or self-made directory listings (PHP >= 4.3.3)
953:
954: You can use PHP to generate the error pages for "404 Not Found" or
955: similar. Add the following line to the object in obj.conf for every
956: error page you want to overwrite:
957: Error fn="php5_execute" code=XXX script="/path/to/script.php" [inikey=value inik
958: ey=value...]
959:
960: where XXX is the HTTP error code. Please delete any other Error
961: directives which could interfere with yours. If you want to place a
962: page for all errors that could exist, leave the code parameter out.
963: Your script can get the HTTP status code with $_SERVER['ERROR_TYPE'].
964:
965: Another possibility is to generate self-made directory listings. Just
966: create a PHP script which displays a directory listing and replace the
967: corresponding default Service line for type="magnus-internal/directory"
968: in obj.conf with the following:
969: Service fn="php5_execute" type="magnus-internal/directory" script="/path/to/scri
970: pt.php" [inikey=value inikey=value...]
971:
972: For both error and directory listing pages the original URI and
973: translated URI are in the variables $_SERVER['PATH_INFO'] and
974: $_SERVER['PATH_TRANSLATED'].
975: __________________________________________________________________
976:
977: Note about nsapi_virtual() and subrequests (PHP >= 4.3.3)
978:
979: The NSAPI module now supports the nsapi_virtual() function (alias:
980: virtual()) to make subrequests on the web server and insert the result
981: in the web page. The problem is, that this function uses some
982: undocumented features from the NSAPI library.
983:
984: Under Unix this is not a problem, because the module automatically
985: looks for the needed functions and uses them if available. If not,
986: nsapi_virtual() is disabled.
987:
988: Under Windows limitations in the DLL handling need the use of a
989: automatic detection of the most recent ns-httpdXX.dll file. This is
990: tested for servers till version 6.1. If a newer version of the Sun
991: server is used, the detection fails and nsapi_virtual() is disabled.
992:
993: If this is the case, try the following: Add the following parameter to
994: php5_init in magnus.conf/obj.conf:
995: Init fn=php5_init ... server_lib="ns-httpdXX.dll"
996:
997: where XX is the correct DLL version number. To get it, look in the
998: server-root for the correct DLL name. The DLL with the biggest filesize
999: is the right one.
1000:
1001: You can check the status by using the phpinfo() function.
1002:
1003: Note: But be warned: Support for nsapi_virtual() is EXPERIMENTAL!!!

1071:
1072: Installation of extensions on Windows
1073:
1074: After installing PHP and a web server on Windows, you will probably
1075: want to install some extensions for added functionality. You can choose
1076: which extensions you would like to load when PHP starts by modifying
1077: your php.ini. You can also load a module dynamically in your script
1078: using dl().
1079:
1080: The DLLs for PHP extensions are prefixed with php_.
1081:
1082: Many extensions are built into the Windows version of PHP. This means
1083: additional DLL files, and the extension directive, are not used to load
1084: these extensions. The Windows PHP Extensions table lists extensions
1085: that require, or used to require, additional PHP DLL files. Here's a
1086: list of built in extensions:
1087:
1088: In PHP 5 (updated PHP 5.0.4), the following changes exist. Built in:
1089: DOM, LibXML, Iconv, SimpleXML, SPL and SQLite. And the following are no
1090: longer built in: MySQL and Overload.
1091:
1092: The default location PHP searches for extensions is C:\php5 in PHP 5.
1093: To change this setting to reflect your setup of PHP edit your php.ini
1094: file:
1095:
1096: * You will need to change the extension_dir setting to point to the
1097: directory where your extensions lives, or where you have placed
1098: your php_*.dll files. For example:
1099:
1100: extension_dir = C:\php\extensions
1101:
1102: * Enable the extension(s) in php.ini you want to use by uncommenting
1103: the extension=php_*.dll lines in php.ini. This is done by deleting
1104: the leading ; from the extension you want to load.
1105:
1106: Example 2-8. Enable Bzip2 extension for PHP-Windows
1107: // change the following line from ...
1108: ;extension=php_bz2.dll
1109:
1110: // ... to
1111: extension=php_bz2.dll
1112:
1113: * Some of the extensions need extra DLLs to work. Couple of them can
1114: be found in the distribution package, in in the main folder in PHP 5,
1115: but some, for example Oracle (php_oci8.dll) require DLLs which are
1116: not bundled with the distribution package.
1117: * Some of these DLLs are not bundled with the PHP distribution. See
1118: each extensions documentation page for details. Also, read the
1119: manual section titled Installation of PECL extensions for details
1120: on PECL. An increasingly large number of PHP extensions are found
1121: in PECL, and these extensions require a separate download.
1122:
1123: Note: If you are running a server module version of PHP remember to
1124: restart your web server to reflect your changes to php.ini.
1125:
1126: The following table describes some of the extensions available and
1127: required additional dlls.

1184: Chapter 3. Installation of PECL extensions
1185:
1186: Introduction to PECL Installations
1187:
1188: PECL is a repository of PHP extensions that are made available to you
1189: via the PEAR packaging system. This section of the manual is intended
1190: to demonstrate how to obtain and install PECL extensions.
1191:
1192: These instructions assume /your/phpsrcdir/ is the path to the PHP
1193: source distribution, and that extname is the name of the PECL
1194: extension. Adjust accordingly. These instructions also assume a
1195: familiarity with the pear command. The information in the PEAR manual
1196: for the pear command also applies to the pecl command.
1197:
1198: To be useful, a shared extension must be built, installed, and loaded.
1199: The methods described below provide you with various instructions on
1200: how to build and install the extensions, but they do not automatically
1201: load them. Extensions can be loaded by adding an extension directive.
1202: To this php.ini file, or through the use of the dl() function.
1203:
1204: When building PHP modules, it's important to have known-good versions
1205: of the required tools (autoconf, automake, libtool, etc.) See the
1206: SVN Instructions for details on the required tools, and required
1207: versions.
1208: __________________________________________________________________
1209:
1210: Downloading PECL extensions
1211:
1212: There are several options for downloading PECL extensions, such as:
1213:
1214: * http://pecl.php.net
1215: The PECL web site contains information about the different
1216: extensions that are offered by the PHP Development Team. The
1217: information available here includes: ChangeLog, release notes,
1218: requirements and other similar details.
1219: * pecl download extname
1220: PECL extensions that have releases listed on the PECL web site are
1221: available for download and installation using the pecl command.
1222: Specific revisions may also be specified.
1223: * SVN
1224: Most PECL extensions also reside in SVN. A web-based view may be
1225: seen at http://svn.php.net/pecl/. To download straight from SVN,
1226: the following sequence of commands may be used.
1227:
1228: $ svn co http://svn.php.net/repository/pecl/<extname>/trunk
1229:
1230: * Windows downloads
1231: Windows users may find compiled PECL binaries by downloading the
1232: Collection of PECL modules from the PHP Downloads page, or by
1233: retrieving a PECL Snapshot or an extension DLL on PECL4WIN. To
1234: compile PHP under Windows, read the appropriate chapter.
1235: __________________________________________________________________
1236:
1237: PECL for Windows users
1238:
1239: As with any other PHP extension DLL, installation is as simple as
1240: copying the PECL extension DLLs into the extension_dir folder and
1241: loading them from php.ini. For example, add the following line to your
1242: php.ini:
1243:
1244: extension=php_extname.dll
1245:
1246: After doing this, restart the web server.
1247: __________________________________________________________________
1248:
1249: Compiling shared PECL extensions with the pecl command
1250:
1251: PECL makes it easy to create shared PHP extensions. Using the pecl
1252: command, do the following:
1253:
1254: $ pecl install extname
1255:
1256: This will download the source for extname, compile, and install
1257: extname.so into your extension_dir. extname.so may then be loaded via
1258: php.ini
1259:
1260: By default, the pecl command will not install packages that are marked
1261: with the alpha or beta state. If no stable packages are available, you
1262: may install a beta package using the following command:
1263:
1264: $ pecl install extname-beta
1265:
1266: You may also install a specific version using this variant:
1267:
1268: $ pecl install extname-0.1
1269: __________________________________________________________________
1270:
1271: Compiling shared PECL extensions with phpize
1272:
1273: Sometimes, using the pecl installer is not an option. This could be
1274: because you're behind a firewall, or it could be because the extension
1275: you want to install is not available as a PECL compatible package, such
1276: as unreleased extensions from SVN. If you need to build such an
1277: extension, you can use the lower-level build tools to perform the build
1278: manually.
1279:
1280: The phpize command is used to prepare the build environment for a PHP
1281: extension. In the following sample, the sources for an extension are in
1282: a directory named extname:
1283:
1284: $ cd extname
1285: $ phpize
1286: $ ./configure
1287: $ make
1288: # make install
1289:
1290: A successful install will have created extname.so and put it into the
1291: PHP extensions directory. You'll need to and adjust php.ini and add an
1292: extension=extname.so line before you can use the extension.
1293:
1294: If the system is missing the phpize command, and precompiled packages
1295: (like RPM's) are used, be sure to also install the appropriate devel
1296: version of the PHP package as they often include the phpize command
1297: along with the appropriate header files to build PHP and its
1298: extensions.
1299:
1300: Execute phpize --help to display additional usage information.
1301: __________________________________________________________________
1302:
1303: Compiling PECL extensions statically into PHP
1304:
1305: You might find that you need to build a PECL extension statically into
1306: your PHP binary. To do this, you'll need to place the extension source
1307: under the php-src/ext/ directory and tell the PHP build system to
1308: regenerate its configure script.
1309:
1310: $ cd /your/phpsrcdir/ext
1311: $ pecl download extname
1312: $ gzip -d < extname.tgz | tar -xvf -
1313: $ mv extname-x.x.x extname
1314:
1315: This will result in the following directory:
1316:
1317: /your/phpsrcdir/ext/extname
1318:
1319: From here, force PHP to rebuild the configure script, and then build
1320: PHP as normal:
1321:
1322: $ cd /your/phpsrcdir
1323: $ rm configure
1324: $ ./buildconf --force
1325: $ ./configure --help
1326: $ ./configure --with-extname --enable-someotherext --with-foobar
1327: $ make
1328: $ make install
1329:
1330: Note: To run the 'buildconf' script you need autoconf 2.13 and
1331: automake 1.4+ (newer versions of autoconf may work, but are not
1332: supported).
1333:
1334: Whether --enable-extname or --with-extname is used depends on the
1335: extension. Typically an extension that does not require external
1336: libraries uses --enable. To be sure, run the following after buildconf:
1337:
1338: $ ./configure --help | grep extname
1339: __________________________________________________________________

1341: Chapter 4. Problems?
1342:
1343: Read the FAQ
1344:
1345: Some problems are more common than others. The most common ones are
1346: listed in the PHP FAQ, part of this manual.
1347: __________________________________________________________________
1348:
1349: Other problems
1350:
1351: If you are still stuck, someone on the PHP installation mailing list
1352: may be able to help you. You should check out the archive first, in
1353: case someone already answered someone else who had the same problem as
1354: you. The archives are available from the support page on
1355: http://www.php.net/support.php. To subscribe to the PHP installation
1356: mailing list, send an empty mail to
1357: php-install-subscribe@lists.php.net. The mailing list address is
1358: php-install@lists.php.net.
1359:
1360: If you want to get help on the mailing list, please try to be precise
1361: and give the necessary details about your environment (which operating
1362: system, what PHP version, what web server, if you are running PHP as
1363: CGI or a server module, safe mode, etc...), and preferably enough code
1364: to make others able to reproduce and test your problem.
1365: __________________________________________________________________
1366:
1367: Bug reports
1368:
1369: If you think you have found a bug in PHP, please report it. The PHP
1370: developers probably don't know about it, and unless you report it,
1371: chances are it won't be fixed. You can report bugs using the
1372: bug-tracking system at http://bugs.php.net/. Please do not send bug
1373: reports in mailing list or personal letters. The bug system is also
1374: suitable to submit feature requests.
1375:
1376: Read the How to report a bug document before submitting any bug
1377: reports!
1378: __________________________________________________________________
1379:
1380: Chapter 5. Runtime Configuration
1381:
1382: The configuration file
1383:
1384: The configuration file (called php3.ini in PHP 3, and simply php.ini as
1385: of PHP 4) is read when PHP starts up. For the server module versions of
1386: PHP, this happens only once when the web server is started. For the CGI
1387: and CLI version, it happens on every invocation.
1388:
1389: php.ini is searched in these locations (in order):
1390:
1391: * SAPI module specific location (PHPIniDir directive in Apache 2, -c
1392: command line option in CGI and CLI, php_ini parameter in NSAPI,
1393: PHP_INI_PATH environment variable in THTTPD)
1394: * The PHPRC environment variable. Before PHP 5.2.0 this was checked
1395: after the registry key mentioned below.
1396: * As of PHP 5.2.0, the following registry locations are searched in
1397: order: HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x.y.z\IniFilePath,
1398: HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x.y\IniFilePath and
1399: HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x\IniFilePath, where x, y and z
1400: mean the PHP major, minor and release versions.
1401: * HKEY_LOCAL_MACHINE\SOFTWARE\PHP\IniFilePath (Windows Registry
1402: location)
1403: * Current working directory (except CLI)
1404: * The web server's directory (for SAPI modules), or directory of PHP
1405: (otherwise in Windows)
1406: * Windows directory (C:\windows or C:\winnt) (for Windows), or
1407: --with-config-file-path compile time option
1408:
1409: If php-SAPI.ini exists (where SAPI is used SAPI, so the filename is
1410: e.g. php-cli.ini or php-apache.ini), it's used instead of php.ini. SAPI
1411: name can be determined by php_sapi_name().
1412:
1413: Note: The Apache web server changes the directory to root at startup
1414: causing PHP to attempt to read php.ini from the root filesystem if
1415: it exists.
1416:
1417: The php.ini directives handled by extensions are documented
1418: respectively on the pages of the extensions themselves. The list of the
1419: core directives is available in the appendix. Probably not all PHP
1420: directives are documented in the manual though. For a complete list of
1421: directives available in your PHP version, please read your well
1422: commented php.ini file. Alternatively, you may find the latest
1423: php.ini from SVN helpful too.
1424:
1425: Example 5-1. php.ini example
1426: ; any text on a line after an unquoted semicolon (;) is ignored
1427: [php] ; section markers (text within square brackets) are also ignored
1428: ; Boolean values can be set to either:
1429: ; true, on, yes
1430: ; or false, off, no, none
1431: html_errors = off
1432: track_errors = yes
1433:
1434: ; you can enclose strings in double-quotes
1435: include_path = ".:/usr/local/lib/php"
1436:
1437: ; backslashes are treated the same as any other character
1438: include_path = ".;c:\php\lib"
1439:
1440: Since PHP 5.1.0, it is possible to refer to existing .ini variables
1441: from within .ini files. Example: open_basedir = ${open_basedir}
1442: ":/new/dir".

1445: How to change configuration settings
1446:
1447: Running PHP as an Apache module
1448:
1449: When using PHP as an Apache module, you can also change the
1450: configuration settings using directives in Apache configuration files
1451: (e.g. httpd.conf) and .htaccess files. You will need "AllowOverride
1452: Options" or "AllowOverride All" privileges to do so.
1453:
1454: With PHP 4 and PHP 5, there are several Apache directives that allow
1455: you to change the PHP configuration from within the Apache
1456: configuration files. For a listing of which directives are PHP_INI_ALL,
1457: PHP_INI_PERDIR, or PHP_INI_SYSTEM, have a look at the List of php.ini
1458: directives appendix.
1459:
1460: Note: With PHP 3, there are Apache directives that correspond to
1461: each configuration setting in the php3.ini name, except the name is
1462: prefixed by "php3_".
1463:
1464: php_value name value
1465: Sets the value of the specified directive. Can be used only with
1466: PHP_INI_ALL and PHP_INI_PERDIR type directives. To clear a
1467: previously set value use none as the value.
1468:
1469: Note: Don't use php_value to set boolean values. php_flag (see
1470: below) should be used instead.
1471:
1472: php_flag name on|off
1473: Used to set a boolean configuration directive. Can be used only
1474: with PHP_INI_ALL and PHP_INI_PERDIR type directives.
1475:
1476: php_admin_value name value
1477: Sets the value of the specified directive. This can not be used
1478: in .htaccess files. Any directive type set with php_admin_value
1479: can not be overridden by .htaccess or virtualhost directives. To
1480: clear a previously set value use none as the value.
1481:
1482: php_admin_flag name on|off
1483: Used to set a boolean configuration directive. This can not be
1484: used in .htaccess files. Any directive type set with
1485: php_admin_flag can not be overridden by .htaccess or virtualhost
1486: directives.
1487:
1488: Example 5-2. Apache configuration example
1489: <IfModule mod_php5.c>
1490: php_value include_path ".:/usr/local/lib/php"
1491: php_admin_flag engine on
1492: </IfModule>
1493:
1494: Caution
1495:
1496: PHP constants do not exist outside of PHP. For example, in httpd.conf
1497: you can not use PHP constants such as E_ALL or E_NOTICE to set the
1498: error_reporting directive as they will have no meaning and will
1499: evaluate to 0. Use the associated bitmask values instead. These
1500: constants can be used in php.ini
1501: __________________________________________________________________
1502:
1503: Changing PHP configuration via the Windows registry
1504:
1505: When running PHP on Windows, the configuration values can be modified
1506: on a per-directory basis using the Windows registry. The configuration
1507: values are stored in the registry key HKLM\SOFTWARE\PHP\Per Directory
1508: Values, in the sub-keys corresponding to the path names. For example,
1509: configuration values for the directory c:\inetpub\wwwroot would be
1510: stored in the key HKLM\SOFTWARE\PHP\Per Directory
1511: Values\c\inetpub\wwwroot. The settings for the directory would be
1512: active for any script running from this directory or any subdirectory
1513: of it. The values under the key should have the name of the PHP
1514: configuration directive and the string value. PHP constants in the
1515: values are not parsed. However, only configuration values changeable in
1516: PHP_INI_USER can be set this way, PHP_INI_PERDIR values can not.
1517: __________________________________________________________________
1518:
1519: Other interfaces to PHP
1520:
1521: Regardless of how you run PHP, you can change certain values at runtime
1522: of your scripts through ini_set(). See the documentation on the
1523: ini_set() page for more information.
1524:
1525: If you are interested in a complete list of configuration settings on
1526: your system with their current values, you can execute the phpinfo()
1527: function, and review the resulting page. You can also access the values
1528: of individual configuration directives at runtime using ini_get() or
1529: get_cfg_var().

1532: Chapter 6. Installation FAQ
1533:
1534: This section holds common questions about the way to install PHP. PHP
1535: is available for almost any OS (except maybe for MacOS before OSX), and
1536: almost any web server.
1537:
1538: To install PHP, follow the instructions in Installing PHP.
1539:
1540: 1. Why shouldn't I use Apache2 with a threaded MPM in a production
1541: environment?
1542:
1543: 2. Unix/Windows: Where should my php.ini file be located?
1544: 3. Unix: I installed PHP, but every time I load a document, I get the
1545: message 'Document Contains No Data'! What's going on here?
1546:
1547: 4. Unix: I installed PHP using RPMS, but Apache isn't processing the
1548: PHP pages! What's going on here?
1549:
1550: 5. Unix: I installed PHP 3 using RPMS, but it doesn't compile with the
1551: database support I need! What's going on here?
1552:
1553: 6. Unix: I patched Apache with the FrontPage extensions patch, and
1554: suddenly PHP stopped working. Is PHP incompatible with the
1555: Apache FrontPage extensions?
1556:
1557: 7. Unix/Windows: I have installed PHP, but when I try to access a PHP
1558: script file via my browser, I get a blank screen.
1559:
1560: 8. Unix/Windows: I have installed PHP, but when try to access a PHP
1561: script file via my browser, I get a server 500 error.
1562:
1563: 9. Some operating systems: I have installed PHP without errors, but
1564: when I try to start apache I get undefined symbol errors:
1565:
1566: [mybox:user /src/php5] root# apachectl configtest
1567: apachectl: /usr/local/apache/bin/httpd Undefined symbols:
1568: _compress
1569: _uncompress
1570:
1571: 10. Windows: I have installed PHP, but when I to access a PHP script
1572: file via my browser, I get the error:
1573:
1574: cgi error:
1575: The specified CGI application misbehaved by not
1576: returning a complete set of HTTP headers.
1577: The headers it did return are:
1578:
1579: 11. Windows: I've followed all the instructions, but still can't get
1580: PHP and IIS to work together!
1581:
1582: 12. When running PHP as CGI with IIS, PWS, OmniHTTPD or Xitami, I get
1583: the following error: Security Alert! PHP CGI cannot be accessed
1584: directly..
1585:
1586: 13. How do I know if my php.ini is being found and read? It seems like
1587: it isn't as my changes aren't being implemented.
1588:
1589: 14. How do I add my PHP directory to the PATH on Windows?
1590: 15. How do I make the php.ini file available to PHP on windows?
1591: 16. Is it possible to use Apache content negotiation (MultiViews
1592: option) with PHP?
1593:
1594: 17. Is PHP limited to process GET and POST request methods only?
1595:
1596: 1. Why shouldn't I use Apache2 with a threaded MPM in a production
1597: environment?
1598:
1599: PHP is glue. It is the glue used to build cool web applications by
1600: sticking dozens of 3rd-party libraries together and making it all
1601: appear as one coherent entity through an intuitive and easy to learn
1602: language interface. The flexibility and power of PHP relies on the
1603: stability and robustness of the underlying platform. It needs a working
1604: OS, a working web server and working 3rd-party libraries to glue
1605: together. When any of these stop working PHP needs ways to identify the
1606: problems and fix them quickly. When you make the underlying framework
1607: more complex by not having completely separate execution threads,
1608: completely separate memory segments and a strong sandbox for each
1609: request to play in, feet of clay are introduced into PHP's system.
1610:
1611: If you feel you have to use a threaded MPM, look at a FastCGI
1612: configuration where PHP is running in its own memory space.
1613:
1614: And finally, this warning against using a threaded MPM is not as strong
1615: for Windows systems because most libraries on that platform tend to be
1616: threadsafe.
1617:
1618: 2. Unix/Windows: Where should my php.ini file be located?
1619:
1620: By default on Unix it should be in /usr/local/lib which is
1621: <install-path>/lib. Most people will want to change this at
1622: compile-time with the --with-config-file-path flag. You would, for
1623: example, set it with something like:
1624: --with-config-file-path=/etc
1625:
1626: And then you would copy php.ini-production from the distribution to
1627: /etc/php.ini and edit it to make any local changes you want.
1628: --with-config-file-scan-dir=PATH
1629:
1630: On Windows the default path for the php.ini file is the Windows
1631: directory. If you're using the Apache webserver, php.ini is first
1632: searched in the Apaches install directory, e.g. c:\program files\apache
1633: group\apache. This way you can have different php.ini files for
1634: different versions of Apache on the same machine.
1635:
1636: See also the chapter about the configuration file.
1637:
1638: 3. Unix: I installed PHP, but every time I load a document, I get the
1639: message 'Document Contains No Data'! What's going on here?
1640:
1641: This probably means that PHP is having some sort of problem and is
1642: core-dumping. Look in your server error log to see if this is the case,
1643: and then try to reproduce the problem with a small test case. If you
1644: know how to use 'gdb', it is very helpful when you can provide a
1645: backtrace with your bug report to help the developers pinpoint the
1646: problem. If you are using PHP as an Apache module try something like:
1647:
1648: * Stop your httpd processes
1649: * gdb httpd
1650: * Stop your httpd processes
1651: * > run -X -f /path/to/httpd.conf
1652: * Then fetch the URL causing the problem with your browser
1653: * > run -X -f /path/to/httpd.conf
1654: * If you are getting a core dump, gdb should inform you of this now
1655: * type: bt
1656: * You should include your backtrace in your bug report. This should
1657: be submitted to http://bugs.php.net/
1658:
1659: If your script uses the regular expression functions (ereg() and
1660: friends), you should make sure that you compiled PHP and Apache with
1661: the same regular expression package. This should happen automatically
1662: with PHP and Apache 1.3.x
1663:
1664: 4. Unix: I installed PHP using RPMS, but Apache isn't processing the
1665: PHP pages! What's going on here?
1666:
1667: Assuming you installed both Apache and PHP from RPM packages, you need
1668: to uncomment or add some or all of the following lines in your
1669: httpd.conf file:
1670: # Extra Modules
1671: AddModule mod_php.c
1672: AddModule mod_php3.c
1673: AddModule mod_perl.c
1674:
1675: # Extra Modules
1676: LoadModule php_module modules/mod_php.so
1677: LoadModule perl_module modules/libperl.so
1678:
1679: And add:
1680: AddType application/x-httpd-php3 .php3 # for PHP 3
1681: AddType application/x-httpd-php .php # for PHP 4
1682:
1683: ... to the global properties, or to the properties of the VirtualDomain
1684: you want to have PHP support added to.
1685:
1686: 5. Unix: I installed PHP 3 using RPMS, but it doesn't compile with the
1687: database support I need! What's going on here?
1688:
1689: Due to the way PHP 3 built, it is not easy to build a complete flexible
1690: PHP RPM. This issue is addressed in PHP 4. For PHP 3, we currently
1691: suggest you use the mechanism described in the INSTALL.REDHAT file in
1692: the PHP distribution. If you insist on using an RPM version of PHP 3,
1693: read on...
1694:
1695: The RPM packagers are setting up the RPMS to install without database
1696: support to simplify installations and because RPMS use /usr/ instead of
1697: the standard /usr/local/ directory for files. You need to tell the RPM
1698: spec file which databases to support and the location of the top-level
1699: of your database server.
1700:
1701: This example will explain the process of adding support for the popular
1702: MySQL database server, using the mod installation for Apache.
1703:
1704: Of course all of this information can be adjusted for any database
1705: server that PHP supports. We will assume you installed MySQL and Apache
1706: completely with RPMS for this example as well.
1707:
1708: * First remove mod_php3 :
1709:
1710: rpm -e mod_php3
1711:
1712: * Then get the source rpm and INSTALL it, NOT --rebuild
1713:
1714: rpm -Uvh mod_php3-3.0.5-2.src.rpm
1715:
1716: * Then edit the /usr/src/redhat/SPECS/mod_php3.spec file
1717: In the %build section add the database support you want, and the
1718: path.
1719: For MySQL you would add --with-mysql=/usr The %build section will
1720: look something like this:
1721:
1722: ./configure --prefix=/usr \
1723: --with-apxs=/usr/sbin/apxs \
1724: --with-config-file-path=/usr/lib \
1725: --enable-debug=no \
1726: --enable-safe-mode \
1727: --with-exec-dir=/usr/bin \
1728: --with-mysql=/usr \
1729: --with-system-regex
1730:
1731: * Once this modification is made then build the binary rpm as
1732: follows:
1733:
1734: rpm -bb /usr/src/redhat/SPECS/mod_php3.spec
1735:
1736: * Then install the rpm
1737:
1738: rpm -ivh /usr/src/redhat/RPMS/i386/mod_php3-3.0.5-2.i386.rpm
1739:
1740: Make sure you restart Apache, and you now have PHP 3 with MySQL support
1741: using RPM's. Note that it is probably much easier to just build from
1742: the distribution tarball of PHP 3 and follow the instructions in
1743: INSTALL.REDHAT found in that distribution.
1744:
1745: 6. Unix: I patched Apache with the FrontPage extensions patch, and
1746: suddenly PHP stopped working. Is PHP incompatible with the Apache
1747: FrontPage extensions?
1748:
1749: No, PHP works fine with the FrontPage extensions. The problem is that
1750: the FrontPage patch modifies several Apache structures, that PHP relies
1751: on. Recompiling PHP (using 'make clean ; make') after the FP patch is
1752: applied would solve the problem.
1753:
1754: 7. Unix/Windows: I have installed PHP, but when I try to access a PHP
1755: script file via my browser, I get a blank screen.
1756:
1757: Do a 'view source' in the web browser and you will probably find that
1758: you can see the source code of your PHP script. This means that the web
1759: server did not send the script to PHP for interpretation. Something is
1760: wrong with the server configuration - double check the server
1761: configuration against the PHP installation instructions.
1762:
1763: 8. Unix/Windows: I have installed PHP, but when try to access a PHP
1764: script file via my browser, I get a server 500 error.
1765:
1766: Something went wrong when the server tried to run PHP. To get to see a
1767: sensible error message, from the command line, change to the directory
1768: containing the PHP executable (php.exe on Windows) and run php -i. If
1769: PHP has any problems running, then a suitable error message will be
1770: displayed which will give you a clue as to what needs to be done next.
1771: If you get a screen full of HTML codes (the output of the phpinfo()
1772: function) then PHP is working, and your problem may be related to your
1773: server configuration which you should double check.
1774:
1775: 9. Some operating systems: I have installed PHP without errors, but
1776: when I try to start apache I get undefined symbol errors:
1777: [mybox:user /src/php5] root# apachectl configtest
1778: apachectl: /usr/local/apache/bin/httpd Undefined symbols:
1779: _compress
1780: _uncompress
1781:
1782: This has actually nothing to do with PHP, but with the MySQL client
1783: libraries. Some need --with-zlib, others do not. This is also covered
1784: in the MySQL FAQ.
1785:
1786: 10. Windows: I have installed PHP, but when I to access a PHP script
1787: file via my browser, I get the error:
1788: cgi error:
1789: The specified CGI application misbehaved by not
1790: returning a complete set of HTTP headers.
1791: The headers it did return are:
1792:
1793: This error message means that PHP failed to output anything at all. To
1794: get to see a sensible error message, from the command line, change to
1795: the directory containing the PHP executable (php.exe on Windows) and
1796: run php -i. If PHP has any problems running, then a suitable error
1797: message will be displayed which will give you a clue as to what needs
1798: to be done next. If you get a screen full of HTML codes (the output of
1799: the phpinfo() function) then PHP is working.
1800:
1801: Once PHP is working at the command line, try accessing the script via
1802: the browser again. If it still fails then it could be one of the
1803: following:
1804:
1805: * File permissions on your PHP script, php.exe, php5ts.dll, php.ini
1806: or any PHP extensions you are trying to load are such that the
1807: anonymous internet user ISUR_<machinename> cannot access them.
1808: * The script file does not exist (or possibly isn't where you think
1809: it is relative to your web root directory). Note that for IIS you
1810: can trap this error by ticking the 'check file exists' box when
1811: setting up the script mappings in the Internet Services Manager. If
1812: a script file does not exist then the server will return a 404
1813: error instead. There is also the additional benefit that IIS will
1814: do any authentication required for you based on the NTLanMan
1815: permissions on your script file.
1816:
1817: 11. Windows: I've followed all the instructions, but still can't get
1818: PHP and IIS to work together!
1819:
1820: Make sure any user who needs to run a PHP script has the rights to run
1821: php.exe! IIS uses an anonymous user which is added at the time IIS is
1822: installed. This user needs rights to php.exe. Also, any authenticated
1823: user will also need rights to execute php.exe. And for IIS4 you need to
1824: tell it that PHP is a script engine. Also, you will want to read this
1825: faq.
1826:
1827: 12. When running PHP as CGI with IIS, PWS, OmniHTTPD or Xitami, I get
1828: the following error: Security Alert! PHP CGI cannot be accessed
1829: directly..
1830:
1831: You must set the cgi.force_redirect directive to 0. It defaults to 1 so
1832: be sure the directive isn't commented out (with a ;). Like all
1833: directives, this is set in php.ini
1834:
1835: Because the default is 1, it's critical that you're 100% sure that the
1836: correct php.ini file is being read. Read this faq for details.
1837:
1838: 13. How do I know if my php.ini is being found and read? It seems like
1839: it isn't as my changes aren't being implemented.
1840:
1841: To be sure your php.ini is being read by PHP, make a call to phpinfo()
1842: and near the top will be a listing called Configuration File (php.ini).
1843: This will tell you where PHP is looking for php.ini and whether or not
1844: it's being read. If just a directory PATH exists than it's not being
1845: read and you should put your php.ini in that directory. If php.ini is
1846: included within the PATH than it is being read.
1847:
1848: If php.ini is being read and you're running PHP as a module, then be
1849: sure to restart your web server after making changes to php.ini
1850:
1851: 14. How do I add my PHP directory to the PATH on Windows?
1852:
1853: On Windows NT, 2000, XP and 2003:
1854:
1855: * Go to Control Panel and open the System icon (Start -> Settings ->
1856: Control Panel -> System, or just Start -> Control Panel -> System
1857: for Windows XP/2003)
1858: * Go to the Advanced tab
1859: * Click on the 'Environment Variables' button
1860: * Look into the 'System Variables' pane
1861: * Find the Path entry (you may need to scroll to find it)
1862: * Double click on the Path entry
1863: * Enter your PHP directory at the end, including ';' before (e.g.
1864: ;C:\php)
1865: * Press OK and restart your computer
1866:
1867: On Windows 98/Me you need to edit the autoexec.bat file:
1868:
1869: * Open the Notepad (Start -> Run and enter notepad)
1870: * Open the C:\autoexec.bat file
1871: * Locate the line with PATH=C:\WINDOWS;C:\WINDOWS\COMMAND;..... and
1872: add: ;C:\php to the end of the line
1873: * Save the file and restart your computer
1874:
1875: Note: Be sure to reboot after following the steps above to ensure
1876: that the PATH changes are applied.
1877:
1878: The PHP manual used to promote the copying of files into the Windows
1879: system directory, this is because this directory (C:\Windows, C:\WINNT,
1880: etc.) is by default in the systems PATH. Copying files into the Windows
1881: system directory has long since been deprecated and may cause problems.
1882:
1883: 15. How do I make the php.ini file available to PHP on windows?
1884:
1885: There are several ways of doing this. If you are using Apache, read
1886: their installation specific instructions (Apache 1, Apache 2),
1887: otherwise you must set the PHPRC environment variable:
1888:
1889: On Windows NT, 2000, XP and 2003:
1890:
1891: * Go to Control Panel and open the System icon (Start -> Settings ->
1892: Control Panel -> System, or just Start -> Control Panel -> System
1893: for Windows XP/2003)
1894: * Go to the Advanced tab
1895: * Click on the 'Environment Variables' button
1896: * Look into the 'System variables' pane
1897: * Click on 'New' and enter 'PHPRC' as the variable name and the
1898: directory where php.ini is located as the variable value (e.g.
1899: C:\php)
1900: * Press OK and restart your computer
1901:
1902: On Windows 98/Me you need to edit the autoexec.bat file:
1903:
1904: * Open the Notepad (Start -> Run and enter notepad)
1905: * Open the C:\autoexec.bat file
1906: * Add a new line to the end of the file: set PHPRC=C:\php (replace
1907: C:\php with the directory where php.ini is located). Please note
1908: that the path cannot contain spaces. For instance, if you have
1909: installed PHP in C:\Program Files\PHP, you would enter
1910: C:\PROGRA~1\PHP instead.
1911: * Save the file and restart your computer
1912:
1913: 16. Is it possible to use Apache content negotiation (MultiViews
1914: option) with PHP?
1915:
1916: If links to PHP files include extension, everything works perfect. This
1917: FAQ is only for the case when links to PHP files don't include
1918: extension and you want to use content negotiation to choose PHP files
1919: from URL with no extension. In this case, replace the line AddType
1920: application/x-httpd-php .php with:
1921: # PHP 4
1922: AddHandler php-script php
1923: AddType text/html php
1924:
1925: # PHP 5
1926: AddHandler php5-script php
1927: AddType text/html php
1928:
1929: This solution doesn't work for Apache 1 as PHP module doesn't catch
1930: php-script.
1931:
1932: 17. Is PHP limited to process GET and POST request methods only?
1933:
1934: No, it is possible to handle any request method, e.g. CONNECT. Proper
1935: response status can be sent with header(). If only GET and POST methods
1936: should be handled, it can be achieved with this Apache configuration:
1937: <LimitExcept GET POST>
1938: Deny from all
1939: </LimitExcept>
