1.1 misho 34:
35: =============================
1.1.1.2 misho 36: 1. Changes to INI directives
1.1 misho 37: =============================
38:
1.1.1.2 misho 39: - PHP 5.4 now checks at compile time if /dev/urandom or /dev/arandom
1.1.1.3 ! misho 40: are present. If either is available, session.entropy_file now
1.1.1.2 misho 41: defaults to that file and session.entropy_length defaults to 32.
1.1.1.3 ! misho 42: This provides non-blocking entropy to session id generation. If you
1.1.1.2 misho 43: do not want extra entropy for your session ids, add:
44:
45: session.entropy_file=
46: session.entropy_length=0
47:
48: to your php.ini to preserve pre-PHP 5.4 behavior.
49:
50: - Deprecated php.ini directives will now throw an E_CORE_WARNING's
51: instead of the previous E_WARNING's.
52:
53: - The following php.ini directives are no longer available in PHP 5.4
54: and will now throw an E_CORE_ERROR upon startup:
55: - allow_call_time_pass_reference
56: - define_syslog_variables
57: - highlight.bg
58: - magic_quotes_gpc
59: - magic_quotes_runtime
60: - magic_quotes_sybase
61: - register_globals
62: - register_long_arrays
63: - safe_mode
64: - safe_mode_gid
65: - safe_mode_include_dir
66: - safe_mode_exec_dir
67: - safe_mode_allowed_env_vars
68: - safe_mode_protected_env_vars
69: - session.bug_compat_42
70: - session.bug_compat_warn
71: - y2k_compliance
72: - zend.ze1_compatibility_mode
73:
74: - the following new php.ini directives were added:
75: - max_input_vars - specifies how many GET/POST/COOKIE input
76: variables may be accepted. The default value is 1000.
77:
78: - E_ALL now includes E_STRICT.
79:
80: - The recommended production value for error_reporting changed to E_ALL &
81: ~E_DEPRECATED & ~E_STRICT.
82:
83: - Added new session support directives:
84: session.upload_progress.enabled
85: session.upload_progress.cleanup
86: session.upload_progress.prefix
87: session.upload_progress.name
88: session.upload_progress.freq
89: session.upload_progress.min_freq
90:
91: - Added a zend.multibyte directive as a replacement of the PHP compile time
1.1.1.3 ! misho 92: configuration option --enable-zend-multibyte. Now the Zend Engine always
1.1.1.2 misho 93: contains code for multibyte support, which can be enabled or disabled at
1.1.1.3 ! misho 94: runtime. Note: It doesn't make a lot of sense to enable this option if
1.1.1.2 misho 95: ext/mbstring is not enabled, because most functionality is implemented by
96: mbstrings callbacks.
97:
98: - Added zend.script_encoding. This value will be used unless a
99: "declare(encoding=...)" directive appears at the top of the script.
100:
101: - Added zend.signal_check to check for replaced signal handlers on shutdown
102:
103: - Added enable_post_data_reading, which is enabled by default. When it's
104: disabled, the POST data is not read (or processed); the behavior is similar
105: to that of other request methods with body, like PUT. This allows reading
106: the raw POST data in multipart requests and reading/processing the POST data
107: in a stream fashion (through php://input) without having it copied in memory
108: multiple times.
109:
1.1.1.3 ! misho 110: - Added windows_show_crt_warning. This directive shows the CRT warnings when
1.1.1.2 misho 111: enabled. These warnings were displayed by default until now. It is disabled
112: by default.
113:
114: - Added cli.pager to set a pager for CLI interactive shell output.
115:
116: - Added cli.prompt to configure the CLI interactive shell prompt.
117:
118: - Added cli_server.color to enable the CLI web server to use ANSI color coding
119: in terminal output.
120:
121: ========================================
122: 2. Changes to reserved words and classes
123: ========================================
1.1 misho 124:
1.1.1.2 misho 125: - "callable", "insteadof" and "trait" are now reserved words.
1.1 misho 126:
1.1.1.2 misho 127: =============================
128: 3. Changes to engine behavior
129: =============================
1.1 misho 130:
1.1.1.2 misho 131: - The __construct arguments of an extended abstract constructor must
132: now match:
1.1 misho 133:
1.1.1.2 misho 134: abstract class Base
135: {
136: abstract public function __construct();
137: }
138: class Foo extends Base
139: {
140: public function __construct($bar) {}
141: }
142:
143: This now emits a Fatal error due the incompatible declaration.
144:
145: - In previous versions, superglobal names could be used for parameter
146: names, thereby shadowing the corresponding superglobal. In PHP 5.4
147: this now causes a fatal error such as "Cannot re-assign auto-global
148: variable GLOBALS".
149:
150: - Turning null, false or an empty string into an object by adding a
151: property will now emit a warning instead of an E_STRICT error.
152:
153: $test = null;
154: $test->baz = 1;
155:
156: To create a generic object you can use StdClass:
157:
158: $test = new StdClass;
159: $test->baz = 1;
160:
161: - Converting an array to a string now will cause an E_NOTICE warning.
162:
163: - Non-numeric string offsets, e.g. $a['foo'] where $a is a string, now
164: return false on isset() and true on empty(), and produce warning if
1.1.1.3 ! misho 165: trying to use them. Offsets of types double, bool and null produce
1.1.1.2 misho 166: notice. Numeric strings ($a['2']) still work as before.
167:
168: Note that offsets like '12.3' and '5 and a half' are considered
169: non-numeric and produce warning, but are converted to 12 and 5
170: respectively for backwards compatibility reasons.
171:
1.1.1.3 ! misho 172: - Long numeric strings that do not fit in integer or double (such as
! 173: "92233720368547758070") are compared using string comparison if
! 174: they could otherwise result in precision loss - since 5.4.4.
! 175:
1.1.1.2 misho 176: - Closures now support scopes and $this and can be rebound to
177: objects using Closure::bind() and Closure::bindTo().
178:
179: - <?= is now always available regardless of the short_open_tag
180: setting.
181:
182: - Parse error messages are changed to contain more information about
183: the error.
184:
1.1.1.3 ! misho 185: - __clone and __destruct since 5.4.4 follow the same scoping rules as
! 186: the rest of the methods (see bug #61782 for details).
! 187:
1.1.1.2 misho 188: ================================
189: 4. Changes to existing functions
190: ================================
191:
192: - array_combine now returns array() instead of FALSE when two empty arrays are
193: provided as parameters.
194:
195: - dns_get_record() has an extra parameter which allows requesting DNS records
196: by numeric type and makes the result include only the raw data of the
197: response.
198:
199: - call_user_func_array() no longer allows call-time pass by reference.
200:
201: - the default character set for htmlspecialchars() and htmlentities() is
202: now UTF-8. In previous versions it was ISO-8859-1. Note that changing
203: your output charset via the php.ini default_charset directive does not
204: affect htmlspecialchars/htmlentities unless you are passing "" (an
205: empty string) as the encoding parameter to your htmlspecialchars/htmlentities
206: calls.
207:
208: - htmlentities() and htmlspecialchars() are stricter in the code units they
209: accept for the asian encodings. For Big5-HKSCS, the octets 0x80 and 0xFF are
1.1.1.3 ! misho 210: rejected. For GB2312/EUC-CN, the octets 0x8E, 0x8F, 0xA0 and 0xFF are
1.1.1.2 misho 211: rejected. For SJIS, the octets 0x80, 0xA0, 0xFD, 0xFE and 0xFF are rejected,
212: except maybe after a valid starting byte. For EUC-JP, the octets 0xA0 and
213: 0xFF are rejected.
214:
215: - htmlentities() now emits an E_STRICT warning when used with asian characters,
216: as in that case htmlentities has (and already had before this version) the
217: same functionality as htmlspecialchars.
218:
219: - htmlentities() no longer numerically encodes high characters for single-byte
220: encodings (except when there's actually a corresponding named entity). This
221: behavior was not documented and was inconsistent with that for "UTF-8".
222:
223: - html_entity_decode() and htmlspecialchars_decode() behave more consistently,
224: now decoding entities in malformed strings such as "&&" or "&#&".
225:
226: - htmlentities(), htmlspecialchars(), html_entity_decode(), and
227: htmlspecialchars_decode: Added the flags ENT_HTML401, ENT_XML1, ENT_XHTML,
228: and ENT_HTML5. The behavior of these functions including, but not limited to,
229: the characters that are encoded and the entities that are decoded depend on
230: the document type that is specified by those flags.
231:
232: - htmlentities() and htmlspecialchars() with !$double_encode do more strict
233: checks on the validity of the entities. Numerical entities are checked for a
234: valid range (0 to 0x10FFFF); if the flag ENT_DISALLOWED is given, the
235: validity of such numerical entity in the target document type is also
1.1.1.3 ! misho 236: checked. Named entities are checked for necessary existence in the target
1.1.1.2 misho 237: document type instead of only checking whether they were constituted by
238: alphanumeric characters.
239:
240: - The flag ENT_DISALLOWED was added. In addition to the behavior described in
241: the item before, it also makes htmlentities() and htmlspecialchars()
242: substitute characters that appear literally in the argument string and which
243: are not allowed in the target document type with U+FFFD (UTF-8) or �.
244:
245: - The flag ENT_SUBSTITUTE was added. This flag makes invalid multibyte
246: sequences be replaced by U+FFFD (UTF-8) or &#FFFD; by htmlspecialchars() and
247: htmlentities(). It is an alternative to the default behavior, which just
248: returns an empty string and to ENT_IGNORE, which is a security risk. The
249: behavior follows the recommendations of Unicode Technical Report #36.
250:
251: - htmlspecialchars_decode() and html_entity_decode() now decode ' if the
252: document type is ENT_XML1, ENT_XHTML, or ENT_HTML5.
253:
254: - Charset detection with $charset == '' no longer turns to mbstring's
255: internal encoding defined through mb_internal_encoding(). Only the encoding
256: defined through the php.ini setting mbstring.internal_encoding is considered.
257:
258: - number_format() no longer truncates multibyte decimal points and thousand
259: separators to the first byte.
260:
261: - The third parameter ($matches) to preg_match_all() is now optional. If
262: omitted, the function will simply return the number of times the pattern was
263: matched in the subject and will have no other side effects.
264:
265: - The second argument of scandir() now accepts SCANDIR_SORT_NONE (2) as a
266: possible value. This value results in scandir() performing no sorting: on
267: local filesystems, this allows files to be returned in native filesystem
268: order.
269:
270: - stream_select() now preserves the keys of the passed array, be they numeric or
271: strings. This breaks code that iterated the resulting stream array using a
272: numeric index, but makes easier to identify which of the passed streams are
273: present in the result.
274:
275: - stream_set_write_buffer() no longer disables the read buffer of a plain
276: stream when 0 is given as the second argument.
277:
278: - stream_set_write_buffer() no longer changes the chunk size in socket streams.
279:
280: - fclose() closes streams with resource refcount > 1; it doesn't merely
281: decrement the resource refcount.
282:
283: - socket_set_options() and socket_get_options() now support multicast options.
284:
285: - The raw data parameter in openssl_encrypt() and openssl_decrypt() is now an
286: options integer rather than a boolean. A value of true produces the same
287: behavior.
1.1 misho 288:
289: - Write operations within XSLT (for example with the extension sax:output) are
1.1.1.2 misho 290: disabled by default. You can define what is forbidden with the method
291: XsltProcess::setSecurityPrefs($options).
1.1 misho 292:
1.1.1.2 misho 293: - Added AES support to OpenSSL.
1.1 misho 294:
1.1.1.2 misho 295: - openssl_csr_new() expects the textual data to be in UTF-8.
1.1 misho 296:
1.1.1.2 misho 297: - Added no-padding option to openssl_encrypt() and openssl_decrypt().
1.1 misho 298:
1.1.1.2 misho 299: - Added a "no_ticket" SSL context option to disable the SessionTicket TLS
300: extension.
1.1 misho 301:
1.1.1.2 misho 302: - Added new json_encode() options: JSON_PRETTY_PRINT, JSON_UNESCAPED_SLASHES,
303: JSON_NUMERIC_CHECK, JSON_BIGINT_AS_STRING, JSON_UNESCAPED_UNICODE.
1.1 misho 304:
1.1.1.2 misho 305: - Added Tokyo Cabinet and Berkley DB 5 support to DBA extension.
1.1 misho 306:
1.1.1.2 misho 307: - Added support for CURLOPT_MAX_SEND_SPEED_LARGE and CURLOPT_MAX_RECV_SPEED_LARGE
308: to cURL.
1.1 misho 309:
1.1.1.2 misho 310: - Added optional argument to debug_backtrace() and debug_print_backtrace()
311: to limit the amount of stack frames returned.
1.1 misho 312:
1.1.1.2 misho 313: - Fixed crypt_blowfish handling of 8-bit characters. crypt() in Blowfish mode
314: now supports hashes marked $2a$, $2x$, $2y$ and $2z$.
1.1 misho 315:
1.1.1.2 misho 316: - mbstring now supports following encodings: Shift_JIS/UTF-8 Emoji,
317: JIS X0213:2004 (Shift_JIS-2004, EUC-JP-2004, ISO-2022-JP-2004),
318: MacJapanese (Shift_JIS), gb18030.
1.1 misho 319:
1.1.1.2 misho 320: - Added encode and decode in hex format to mb_encode_numericentity() and
321: mb_decode_numericentity().
1.1 misho 322:
1.1.1.2 misho 323: - Added support for SORT_NATURAL and SORT_FLAG_CASE in array sort functions:
324: sort(), rsort(), ksort(), krsort(), asort(), arsort() and array_multisort().
1.1 misho 325:
1.1.1.2 misho 326: - is_a() and is_subclass_of() now have third boolean parameter, which specifies
327: if the first argument can be a string class name. Default if false for is_a
328: and true for is_subclass_of() for BC reasons.
1.1 misho 329:
1.1.1.2 misho 330: - ob_start() will now treat a chunk size of 1 as meaning 1 byte, rather than
331: the previous special case behavior of treating it as 4096 bytes.
1.1 misho 332:
1.1.1.2 misho 333: - idn_to_ascii() and idn_to_utf8() now take two extra parameters, one indicating
334: the variant (IDNA 2003 or UTS #46) and another, passed by reference, to return
335: details about the operation in case UTS #46 is chosen.
1.1 misho 336:
1.1.1.2 misho 337: - gzencode() used with FORCE_DEFLATE now generates RFC1950 compliant data.
1.1 misho 338:
1.1.1.2 misho 339: - ob_start() no longer starts multiple output buffers when passed
340: array("callback1", "callback2", "callback3", ...).
1.1 misho 341:
1.1.1.3 ! misho 342: - Since 5.4.4, "php://fd" stream syntax is available only in CLI build.
! 343:
! 344: - Since 5.4.5, resourcebundle_create() accepts null for the first two arguments.
! 345:
! 346: - Since 5.4.6, SimpleXMLElement::getDocNamespaces() has and extra parameter which
! 347: allows for toggling if the list of namespaces starts from the document root
! 348: or from the node you call the method on
! 349:
! 350: - Since 5.4.7, ctor is always called when new user stream wrapper object is created.
! 351: Before, it was called only when stream_open was called.
! 352:
1.1.1.2 misho 353: ==============================
354: 5. Changes to existing classes
355: ==============================
1.1 misho 356:
1.1.1.2 misho 357: - Classes that implement stream wrappers can define a method called
358: stream_truncate that will respond to truncation, e.g. through ftruncate.
359: Strictly speaking, this is an addition to the user-space stream wrapper
360: template, not a change to an actual class.
1.1 misho 361:
1.1.1.2 misho 362: - Classes that implement stream wrappers can define a method called
363: stream_metadata that will be called on touch(), chmod(), chgrp(), chown().
1.1 misho 364:
1.1.1.2 misho 365: - Arrays cast from SimpleXMLElement now always contain all nodes instead of
366: just the first matching node.
1.1 misho 367:
1.1.1.2 misho 368: - All SimpleXMLElement children are now always printed when using var_dump(),
369: var_export(), and print_r().
1.1 misho 370:
1.1.1.2 misho 371: - Added iterator support in MySQLi. mysqli_result implements Traversable.
1.1 misho 372:
1.1.1.2 misho 373: ==============================
374: 6. Changes to existing methods
375: ==============================
1.1 misho 376:
1.1.1.2 misho 377: - DateTime::parseFromFormat() now has a "+" modifier to allow trailing text in
378: the string to parse without throwing an error.
1.1 misho 379:
1.1.1.2 misho 380: - Added the ability to pass options to DOMDocument::loadHTML().
1.1 misho 381:
1.1.1.2 misho 382: - FilesystemIterator, GlobIterator and (Recursive)DirectoryIterator now use
383: the default stream context.
1.1 misho 384:
1.1.1.3 ! misho 385: - Since 5.4.5, the constructor of ResourceBundle accepts NULL for the first two
! 386: arguments.
! 387:
1.1.1.2 misho 388: ===========================
389: 7. Deprecated Functionality

1.1 misho 441: ====================
442:
1.1.1.2 misho 443: a. Extensions no longer maintained
1.1 misho 444:
1.1.1.2 misho 445: - ext/sqlite is no longer part of the base distribution and has been moved
1.1.1.3 ! misho 446: to PECL. Use sqlite3 or PDO_SQLITE instead.
1.1 misho 447:
1.1.1.2 misho 448: b. Extensions with changed behavior
1.1 misho 449:
1.1.1.2 misho 450: - The MySQL extensions (ext/mysql, mysqli and PDO_MYSQL) use mysqlnd
451: as the default library now. It is still possible to use libmysql by
452: specifying a path to the configure options.
453:
454: - PDO_MYSQL: Support for linking with MySQL client libraries older
455: than 4.1 is removed.
456:
457: - The session extension now can hook into the file upload feature
458: in order to provide upload progress information through session
459: variables.
460:
461: - SNMP extension
462: - Functions in SNMP extension now returns FALSE on every error
463: condition including SNMP-related (no such instance, end of MIB,
464: etc). Thus, in patricular, breaks previous behavior of get/walk
465: functions returning an empty string on SNMP-related errors.
466: - Multi OID get/getnext/set queries are now supported.
467: - New constants added for use in snmp_set_oid_output_format()
468: function.
469: - Function snmp_set_valueretrieval() changed it's behavior:
470: SNMP_VALUE_OBJECT can be combined with one of
471: SNMP_VALUE_PLAIN or SNMP_VALUE_LIBRARY resulting OID value
472: changes. When no SNMP_VALUE_PLAIN or SNMP_VALUE_LIBRARY
473: is supplied with SNMP_VALUE_OBJECT, SNMP_VALUE_LIBRARY is used.
474: Prior to 5.4.0 when no SNMP_VALUE_PLAIN or SNMP_VALUE_LIBRARY
475: was supplied with SNMP_VALUE_OBJECT, SNMP_VALUE_PLAIN was used.
476: - Added feature-rich OO API (SNMP class)
477: - Dropped UCD-SNMP compatibility code. Consider upgrading to
478: net-snmp v5.3+. Net-SNMP v5.4+ is required for Windows version.
479: - In sake of adding support for IPv6 DNS name resolution of
480: remote SNMP agent (peer) is done by extension now, not by Net-SNMP
481: library anymore.
482:
483: - Date extension
484: - Setting the timezone with the TZ environment variable is no longer
485: supported, instead date.timezone and/or date_default_timezone_set()
486: have to be used.
487: - The extension will no longer guess the default timezone if none
488: is set with date.timezone and/or date_default_timezone_set().
489: Instead it will always fall back to "UTC".
490:
491: - Hash extension
492: - the output of the tiger hash family has been corrected, see
493: https://bugs.php.net/61307
494:
495: ===========================
496: 10. Changes in SAPI support
497: ===========================
498:
499: - A REQUEST_TIME_FLOAT value returns a floating point number indicating the
1.1.1.3 ! misho 500: time with microsecond precision. All SAPIs providing this value should be
1.1.1.2 misho 501: returning float and not time_t.
502:
503: - apache_child_terminate(), getallheaders(), apache_request_headers()
504: and apache_response_headers() are now supported on FastCGI.
505:
506: - The interactive shell allows a shortcut #inisetting=value to change php.ini
507: settings at run-time.
1.1 misho 508:
1.1.1.2 misho 509: - The interactive shell now works with the shared readline extension.
1.1 misho 510:
1.1.1.2 misho 511: - The interactive shell no longer terminates on fatal errors.
1.1 misho 512:
1.1.1.2 misho 513: - A new PHP CLI command line option --rz <name> shows information about the
514: named Zend extension.
1.1 misho 515:
1.1.1.2 misho 516: ===================
517: 11. Windows support
518: ===================
1.1 misho 519:
1.1.1.2 misho 520: - is_link now works properly for symbolic links on Windows Vista
521: or later. Earlier systems do not support symbolic links.
1.1 misho 522:
1.1.1.3 ! misho 523: - As of PHP 5.4.5 and above the COM extension isn't compiled statically in PHP
! 524: anymore but shared. It'll still be delivered with the standard PHP release but
! 525: must be activated manually with the "extension = php_com_dotnet.dll" directive
! 526: in php.ini.
! 527:
! 528: - Apache 2.4 handler is supported as of PHP 5.4.9
