=============================
-1. Reserved words and classes
+1. Changes to INI directives
=============================
-- **namespace** and **goto** are now reserved keywords.
+- PHP 5.4 now checks at compile time if /dev/urandom or /dev/arandom
+ are present. If either is available, session.entropy_file now
+ defaults to that file and session.entropy_length defaults to 32.
+ This provides non-blocking entropy to session id generation. If you
+ do not want extra entropy for your session ids, add:
-- **Closure** is now a reserved class. (Used by lambda and closure.)
+ session.entropy_file=
+ session.entropy_length=0
-=====================================
-2. Changes made to existing functions
-=====================================
+ to your php.ini to preserve pre-PHP 5.4 behavior.
-- Paths containing NULL (like /some/path\0foo.txt) are now considered invalid.
- See http://news.php.net/php.internals/50191
+- Deprecated php.ini directives will now throw an E_CORE_WARNING's
+ instead of the previous E_WARNING's.
-- The HTTP stream wrapper now considers all status codes from 200 to 399 to be
- successful.
+- The following php.ini directives are no longer available in PHP 5.4
+ and will now throw an E_CORE_ERROR upon startup:
+ - allow_call_time_pass_reference
+ - define_syslog_variables
+ - highlight.bg
+ - magic_quotes_gpc
+ - magic_quotes_runtime
+ - magic_quotes_sybase
+ - register_globals
+ - register_long_arrays
+ - safe_mode
+ - safe_mode_gid
+ - safe_mode_include_dir
+ - safe_mode_exec_dir
+ - safe_mode_allowed_env_vars
+ - safe_mode_protected_env_vars
+ - session.bug_compat_42
+ - session.bug_compat_warn
+ - y2k_compliance
+ - zend.ze1_compatibility_mode
-- The array functions natsort(), natcasesort(), usort(), uasort(), uksort(),
- array_flip(), and array_unique() no longer accept objects passed as arguments.
- If you need to use them to access an object's properties, you must cast the
- object to an array first.
+- the following new php.ini directives were added:
+ - max_input_vars - specifies how many GET/POST/COOKIE input
+ variables may be accepted. The default value is 1000.
-- var_dump() output now includes private object members.
+- E_ALL now includes E_STRICT.
-- session_start() now returns FALSE when the session startup fails.
+- The recommended production value for error_reporting changed to E_ALL &
+ ~E_DEPRECATED & ~E_STRICT.
-- property_exists() now checks the existence of a property independent of
- accessibility (like method_exists()).
+- Added new session support directives:
+ session.upload_progress.enabled
+ session.upload_progress.cleanup
+ session.upload_progress.prefix
+ session.upload_progress.name
+ session.upload_progress.freq
+ session.upload_progress.min_freq
-- The $initial parameter for array_reduce can now be of any type.
+- Added a zend.multibyte directive as a replacement of the PHP compile time
+ configuration option --enable-zend-multibyte. Now the Zend Engine always
+ contains code for multibyte support, which can be enabled or disabled at
+ runtime. Note: It doesn't make a lot of sense to enable this option if
+ ext/mbstring is not enabled, because most functionality is implemented by
+ mbstrings callbacks.
-- clearstatcache() no longer clears the realpath cache by default.
+- Added zend.script_encoding. This value will be used unless a
+ "declare(encoding=...)" directive appears at the top of the script.
-- realpath() is no longer system-dependent and works identically on all
- platforms.
+- Added zend.signal_check to check for replaced signal handlers on shutdown
-- call_user_func() now propagates $this even if the callee is the parent class.
+- Added enable_post_data_reading, which is enabled by default. When it's
+ disabled, the POST data is not read (or processed); the behavior is similar
+ to that of other request methods with body, like PUT. This allows reading
+ the raw POST data in multipart requests and reading/processing the POST data
+ in a stream fashion (through php://input) without having it copied in memory
+ multiple times.
-- The filesystem functions opendir(), scandir(), and dir() now use the default
- context if no context argument is passed.
+- Added windows_show_crt_warning. This directive shows the CRT warnings when
+ enabled. These warnings were displayed by default until now. It is disabled
+ by default.
-- The behaviour of functions with by-reference parameters called by value has
- changed. Where previously the function would accept the by-value argument, a
- warning is now emitted and all by-ref parameters are set to NULL.
+- Added cli.pager to set a pager for CLI interactive shell output.
-- There is now native support for the following math functions: asinh(),
- acosh(), atanh(), log1p(), and expm1().
+- Added cli.prompt to configure the CLI interactive shell prompt.
-- In the GD extension, there is now pixelation support available through
- the imagefilter() function.
+- Added cli_server.color to enable the CLI web server to use ANSI color coding
+ in terminal output.
-- crypt() now has Blowfish and extended DES support, and crypt() features are
- now 100% portable. PHP has its own internal crypt implementation which drops
- into place when system support for crypt or crypt_r() is not found.
+========================================
+2. Changes to reserved words and classes
+========================================
-- get_cfg_var() is now able to return "array" INI options.
+- "callable", "insteadof" and "trait" are now reserved words.
-- Stream wrappers can now be used by the include_path INI directive.
+=============================
+3. Changes to engine behavior
+=============================
-- These functions now take new parameters:
- clearstatcache(): $clear_realpath_cache and $filename.
- copy(): $context
- fgetcsv(): $escape
- ini_get_all(): $details
- json_encode(): $options
- json_decode(): $depth
- nl2br(): $is_xhtml
- parse_ini_file(): $scanner_mode
- round(): $mode
- stream_context_create(): $params
- strstr(), stristr(): $before_needle
- sybase_connect(): $new
+- The __construct arguments of an extended abstract constructor must
+ now match:
-- And new mode option for fopen: 'n' (O_NONBLOCK)
+ abstract class Base
+ {
+ abstract public function __construct();
+ }
+ class Foo extends Base
+ {
+ public function __construct($bar) {}
+ }
-- The new mysqlnd library necessitates using MySQL's newer 41-byte password
- format. Continued use of the old 16 byte passwords will cause mysql_connect()
- and other related functions to produce the following error message:
- "mysqlnd cannot connect to MySQL 4.1+ using old authentication"
+ This now emits a Fatal error due the incompatible declaration.
-- The dl() function is now disabled by default, and only available under the
- cli, cgi, and embed SAPIs.
+- In previous versions, superglobal names could be used for parameter
+ names, thereby shadowing the corresponding superglobal. In PHP 5.4
+ this now causes a fatal error such as "Cannot re-assign auto-global
+ variable GLOBALS".
-- mail() now supports the logging of sent mail.
+- Turning null, false or an empty string into an object by adding a
+ property will now emit a warning instead of an E_STRICT error.
-- stream_select(), stream_set_blocking(), stream_set_timeout(), and
- stream_set_write_buffer() now work with user-space stream wrappers.
+ $test = null;
+ $test->baz = 1;
-- getopt() accepts "long options" now on all platforms.
- Optional values and using = as a separator for short options are now
- supported.
+ To create a generic object you can use StdClass:
+ $test = new StdClass;
+ $test->baz = 1;
-===================================
-3. Changes made to existing methods
-===================================
+- Converting an array to a string now will cause an E_NOTICE warning.
-- The magic methods __get(), __set(), __isset(), __unset(), and __call() should
- always be public and can no longer be static. Method signatures are enforced.
+- Non-numeric string offsets, e.g. $a['foo'] where $a is a string, now
+ return false on isset() and true on empty(), and produce warning if
+ trying to use them. Offsets of types double, bool and null produce
+ notice. Numeric strings ($a['2']) still work as before.
-- The __call() magic method is now invoked on access to private and protected
- methods.
+ Note that offsets like '12.3' and '5 and a half' are considered
+ non-numeric and produce warning, but are converted to 12 and 5
+ respectively for backwards compatibility reasons.
-- The __toString() magic method can no longer accept arguments.
+- Long numeric strings that do not fit in integer or double (such as
+ "92233720368547758070") are compared using string comparison if
+ they could otherwise result in precision loss - since 5.4.4.
-- There is a new magic method, __callStatic().
+- Closures now support scopes and $this and can be rebound to
+ objects using Closure::bind() and Closure::bindTo().
-- Internal count() vs. count_elements() handler resolution rules have changed.
- (This could potentially break custom PHP extensions.)
+- <?= is now always available regardless of the short_open_tag
+ setting.
-- The trailing / has been removed from SplFileInfo and other related directory
- classes.
+- Parse error messages are changed to contain more information about
+ the error.
-- SplFileInfo::getpathinfo() now returns information about the path name.
+- __clone and __destruct since 5.4.4 follow the same scoping rules as
+ the rest of the methods (see bug #61782 for details).
-- There are new parameters in:
- Exception::__construct(): $previous
+================================
+4. Changes to existing functions
+================================
-===================================
-4. Changes made to existing classes
-===================================
+- array_combine now returns array() instead of FALSE when two empty arrays are
+ provided as parameters.
-- SplObjectStorage now has ArrayAccess support. It is also now possible to
- store associative information with objects in SplObjectStorage.
-
-=====================
-4.1 New in PHP 5.3.9
-=====================
+- dns_get_record() has an extra parameter which allows requesting DNS records
+ by numeric type and makes the result include only the raw data of the
+ response.
-- Write operations within XSLT (for example with the extension sax:output) are
- disabled by default. You can define what is forbidden with the INI option
- xsl.security_prefs. This option will be marked as deprecated in 5.4 again.
- Use the method XsltProcess::setSecurityPrefs($options) there.
+- call_user_func_array() no longer allows call-time pass by reference.
-- the following new directives were added
+- the default character set for htmlspecialchars() and htmlentities() is
+ now UTF-8. In previous versions it was ISO-8859-1. Note that changing
+ your output charset via the php.ini default_charset directive does not
+ affect htmlspecialchars/htmlentities unless you are passing "" (an
+ empty string) as the encoding parameter to your htmlspecialchars/htmlentities
+ calls.
- - max_input_vars - specifies how many GET/POST/COOKIE input variables may be
- accepted. default value 1000.
+- htmlentities() and htmlspecialchars() are stricter in the code units they
+ accept for the asian encodings. For Big5-HKSCS, the octets 0x80 and 0xFF are
+ rejected. For GB2312/EUC-CN, the octets 0x8E, 0x8F, 0xA0 and 0xFF are
+ rejected. For SJIS, the octets 0x80, 0xA0, 0xFD, 0xFE and 0xFF are rejected,
+ except maybe after a valid starting byte. For EUC-JP, the octets 0xA0 and
+ 0xFF are rejected.
-=============
-5. Deprecated
-=============
+- htmlentities() now emits an E_STRICT warning when used with asian characters,
+ as in that case htmlentities has (and already had before this version) the
+ same functionality as htmlspecialchars.
-- define_syslog_variables() is deprecated.
+- htmlentities() no longer numerically encodes high characters for single-byte
+ encodings (except when there's actually a corresponding named entity). This
+ behavior was not documented and was inconsistent with that for "UTF-8".
-- set_socket_blocking() is deprecated.
+- html_entity_decode() and htmlspecialchars_decode() behave more consistently,
+ now decoding entities in malformed strings such as "&&" or "&#&".
-- call_user_method() and call_user_method_array() are now deprecated. Use
- call_user_func() and call_user_func_array() instead.
+- htmlentities(), htmlspecialchars(), html_entity_decode(), and
+ htmlspecialchars_decode: Added the flags ENT_HTML401, ENT_XML1, ENT_XHTML,
+ and ENT_HTML5. The behavior of these functions including, but not limited to,
+ the characters that are encoded and the entities that are decoded depend on
+ the document type that is specified by those flags.
-- dl() is deprecated.
+- htmlentities() and htmlspecialchars() with !$double_encode do more strict
+ checks on the validity of the entities. Numerical entities are checked for a
+ valid range (0 to 0x10FFFF); if the flag ENT_DISALLOWED is given, the
+ validity of such numerical entity in the target document type is also
+ checked. Named entities are checked for necessary existence in the target
+ document type instead of only checking whether they were constituted by
+ alphanumeric characters.
-- The set_magic_quotes_runtime() function is now deprecated.
+- The flag ENT_DISALLOWED was added. In addition to the behavior described in
+ the item before, it also makes htmlentities() and htmlspecialchars()
+ substitute characters that appear literally in the argument string and which
+ are not allowed in the target document type with U+FFFD (UTF-8) or �.
-- mysql_listtables(), mysql_dropdb(), mysql_createdb(), mysql_list_tables(),
- mysql_drop_db(), and mysql_create_db() are now deprecated.
+- The flag ENT_SUBSTITUTE was added. This flag makes invalid multibyte
+ sequences be replaced by U+FFFD (UTF-8) or &#FFFD; by htmlspecialchars() and
+ htmlentities(). It is an alternative to the default behavior, which just
+ returns an empty string and to ENT_IGNORE, which is a security risk. The
+ behavior follows the recommendations of Unicode Technical Report #36.
-- All ereg functions are now deprecated and emit E_DEPRECATED errors:
- sql_regcase(), spliti(), split(), ereg_replace(), eregi(),
- ereg_replace(), and ereg().
- Use the PCRE family of functions (preg_*()) instead.
+- htmlspecialchars_decode() and html_entity_decode() now decode ' if the
+ document type is ENT_XML1, ENT_XHTML, or ENT_HTML5.
-- mcrypt_generic_end() is deprecated.
+- Charset detection with $charset == '' no longer turns to mbstring's
+ internal encoding defined through mb_internal_encoding(). Only the encoding
+ defined through the php.ini setting mbstring.internal_encoding is considered.
-- mysql_db_query() is deprecated.
+- number_format() no longer truncates multibyte decimal points and thousand
+ separators to the first byte.
-- mysql_escape_string() is deprecated.
+- The third parameter ($matches) to preg_match_all() is now optional. If
+ omitted, the function will simply return the number of times the pattern was
+ matched in the subject and will have no other side effects.
-- session_register(), session_unregister(), and session_is_registered() are now
- deprecated. Use the $_SESSION superglobal array instead.
+- The second argument of scandir() now accepts SCANDIR_SORT_NONE (2) as a
+ possible value. This value results in scandir() performing no sorting: on
+ local filesystems, this allows files to be returned in native filesystem
+ order.
-- Comments starting with '#' are now deprecated in .INI files.
+- stream_select() now preserves the keys of the passed array, be they numeric or
+ strings. This breaks code that iterated the resulting stream array using a
+ numeric index, but makes easier to identify which of the passed streams are
+ present in the result.
-- The following INI directives will now emit an E_DEPRECATED warning
- upon startup if they are activated:
+- stream_set_write_buffer() no longer disables the read buffer of a plain
+ stream when 0 is given as the second argument.
- - define_syslog_variables
- - register_globals
- - register_long_arrays
- - safe_mode
- - magic_quotes_gpc
- - magic_quotes_runtime
- - magic_quotes_sybase
+- stream_set_write_buffer() no longer changes the chunk size in socket streams.
-- The is_dst parameter to mktime() is deprecated.
+- fclose() closes streams with resource refcount > 1; it doesn't merely
+ decrement the resource refcount.
-- Assigning the return value of "new" by reference is deprecated
+- socket_set_options() and socket_get_options() now support multicast options.
-- Call-time pass-by-reference has been deprecated
+- The raw data parameter in openssl_encrypt() and openssl_decrypt() is now an
+ options integer rather than a boolean. A value of true produces the same
+ behavior.
-- Usage of {} to access string offsets is deprecated
+- Write operations within XSLT (for example with the extension sax:output) are
+ disabled by default. You can define what is forbidden with the method
+ XsltProcess::setSecurityPrefs($options).
-- Passing locale category name as string to setlocale() is deprecated.
+- Added AES support to OpenSSL.
-===============
-6. Undeprecated
-===============
+- openssl_csr_new() expects the textual data to be in UTF-8.
-- By popular request, is_a() is no longer deprecated.
+- Added no-padding option to openssl_encrypt() and openssl_decrypt().
-==============
-7. Extensions:
-==============
+- Added a "no_ticket" SSL context option to disable the SessionTicket TLS
+ extension.
- a. moved out to PECL and actively maintained there
+- Added new json_encode() options: JSON_PRETTY_PRINT, JSON_UNESCAPED_SLASHES,
+ JSON_NUMERIC_CHECK, JSON_BIGINT_AS_STRING, JSON_UNESCAPED_UNICODE.
- - fdf
- - ming
- - ncurses
+- Added Tokyo Cabinet and Berkley DB 5 support to DBA extension.
- b. no longer maintained
+- Added support for CURLOPT_MAX_SEND_SPEED_LARGE and CURLOPT_MAX_RECV_SPEED_LARGE
+ to cURL.
- - dbase
- - fbsql
- - msql
- - sybase (use sybase_ct, which is still in PHP core)
- - mhash (hash has full BC layer)
- - mime_magic (use fileinfo, has full BC layer)
+- Added optional argument to debug_backtrace() and debug_print_backtrace()
+ to limit the amount of stack frames returned.
- c. with changed behaviour
+- Fixed crypt_blowfish handling of 8-bit characters. crypt() in Blowfish mode
+ now supports hashes marked $2a$, $2x$, $2y$ and $2z$.
- - dns: dns_check_record() will now return an extra "entries" index,
- containing the TXT elements.
+- mbstring now supports following encodings: Shift_JIS/UTF-8 Emoji,
+ JIS X0213:2004 (Shift_JIS-2004, EUC-JP-2004, ISO-2022-JP-2004),
+ MacJapanese (Shift_JIS), gb18030.
- - datetime: date/time functions will no longer use the TZ environment
- variable to guess which timezone should be used.
+- Added encode and decode in hex format to mb_encode_numericentity() and
+ mb_decode_numericentity().
- - cURL now supports SSH
+- Added support for SORT_NATURAL and SORT_FLAG_CASE in array sort functions:
+ sort(), rsort(), ksort(), krsort(), asort(), arsort() and array_multisort().
- - hash: The SHA-224 and salsa hash algorithms are now supported.
+- is_a() and is_subclass_of() now have third boolean parameter, which specifies
+ if the first argument can be a string class name. Default if false for is_a
+ and true for is_subclass_of() for BC reasons.
- - mbstring: Now supports CP850 encoding.
+- ob_start() will now treat a chunk size of 1 as meaning 1 byte, rather than
+ the previous special case behavior of treating it as 4096 bytes.
- - oci8: Database Resident Connection Pooling (DRCP) and Fast Application
- Notification (FAN) are now supported.
+- idn_to_ascii() and idn_to_utf8() now take two extra parameters, one indicating
+ the variant (IDNA 2003 or UTS #46) and another, passed by reference, to return
+ details about the operation in case UTS #46 is chosen.
- Oracle External Authentication is now supported (except on Windows).
+- gzencode() used with FORCE_DEFLATE now generates RFC1950 compliant data.
- The oci8 function oci_bind_by_name() now supports SQLT_AFC (aka the
- CHAR datatype).
+- ob_start() no longer starts multiple output buffers when passed
+ array("callback1", "callback2", "callback3", ...).
- Calling oci_close() on a persistent connection, or when the variable
- that references a persistent connection goes out of scope, will now
- trigger a roll back of an uncommitted transaction. To avoid unexpected
- behavior explicitly issue a commit or roll back as needed. The old
- behavior can be enabled with the INI directive
- oci8.old_oci_close_semantics.
+- Since 5.4.4, "php://fd" stream syntax is available only in CLI build.
- - openssl: OpenSSL digest and cipher functions are now supported.
- It is also now possible to access the internal values of DSA, RSA and
- DH keys.
+- Since 5.4.5, resourcebundle_create() accepts null for the first two arguments.
- - session: Sessions will no longer store session-files in "/tmp" when
- open_basedir restrictions apply, unless "/tmp" is explicitly added to
- the list of allowed paths.
+- Since 5.4.6, SimpleXMLElement::getDocNamespaces() has and extra parameter which
+ allows for toggling if the list of namespaces starts from the document root
+ or from the node you call the method on
- - SOAP: Now supports sending user-supplied HTTP headers.
+- Since 5.4.7, ctor is always called when new user stream wrapper object is created.
+ Before, it was called only when stream_open was called.
- - MySQLi: Now supports persistent connections by prepending the hostname
- with "p:".
+- Manipulated serialization strings for objects implementing Serializable by
+ replacing "C:" with "O:" at the start will now produce an error.
- - imagepstext now rejects invalid antialiasing steps and raises a warning.
+==============================
+5. Changes to existing classes
+==============================
- d. no longer possible to disable
+- Classes that implement stream wrappers can define a method called
+ stream_truncate that will respond to truncation, e.g. through ftruncate.
+ Strictly speaking, this is an addition to the user-space stream wrapper
+ template, not a change to an actual class.
- - PCRE
- - Reflection
- - SPL
+- Classes that implement stream wrappers can define a method called
+ stream_metadata that will be called on touch(), chmod(), chgrp(), chown().
-==========================
-8. Changes in SAPI support
-==========================
+- Arrays cast from SimpleXMLElement now always contain all nodes instead of
+ just the first matching node.
-- A new "litespeed" SAPI is now available.
+- All SimpleXMLElement children are now always printed when using var_dump(),
+ var_export(), and print_r().
-- FastCGI is now always enabled and can not be disabled. See sapi/cgi/CHANGES
- for more details.
+- Added iterator support in MySQLi. mysqli_result implements Traversable.
-- A new CGI SAPI option, -T, can be used to measure execution time of a script
- repeated several times.
-
-- CGI/FastCGI now has support for .htaccess style user-defined php.ini files.
- See the new user_ini.filename and user_ini.cache_ttl INI directives.
+==============================
+6. Changes to existing methods
+==============================
-============================
-9. Changes in INI directives
-============================
+- DateTime::parseFromFormat() now has a "+" modifier to allow trailing text in
+ the string to parse without throwing an error.
-- zend_extension_debug and zend_extension_ts have been removed. Always use the
- zend_extension directive to load Zend Extensions.
+- Added the ability to pass options to DOMDocument::loadHTML().
-- zend.ze1_compatibility_mode has been removed. If this INI directive is set to
- on, then an E_ERROR is emitted at startup.
+- FilesystemIterator, GlobIterator and (Recursive)DirectoryIterator now use
+ the default stream context.
-- There is now support for special sections: [PATH=/opt/httpd/www.example.com/]
- and [HOST=www.example.com]. Directives set in these sections cannot be
- overridden by user-defined INI files or at runtime.
+- Since 5.4.5, the constructor of ResourceBundle accepts NULL for the first two
+ arguments.
-- Added mbstring.http_output_conv_mimetype. This directive specifies the
- regex pattern of content types for which mb_output_handler() is activated.
+===========================
+7. Deprecated Functionality
+===========================
-- It is now possible to use the full path to load modules using the "extension"
- directive.
+- The following functions are deprecated in PHP 5.4:
+ - mcrypt_generic_end(): use mcrypt_generic_deinit() instead
+ - mysql_list_dbs()
-- "INI variables" can now be used almost anywhere in a php.ini file.
+========================
+8. Removed Functionality
+========================
-- It is now possible to use alphanumeric or variable indices in INI option
- arrays.
+a. Removed features
-- open_basedir is now PHP_INI_ALL
+ The following features have been removed from PHP 5.4:
-- Runtime tightening of open_basedir restrictions is now possible.
+ - Magic quotes
+ - Register globals
+ - Safe mode
+ - Session extension bug compatibility mode
+ - Y2K compliance mode
-- The default value of session.use_only_cookies has changed to "1".
+b. Removed functions
-- The default value of oci8.default_prefetch has been changed from 10 to 100.
+ The following functions are no longer available in PHP 5.4:
-- A new directive, request_order, controls the behavior of $_REQUEST
- independently of variables_order.
-- A new directive, called windows.show_crt_warning, has been introduced.
- This directive shows the CRT warnings when enabled. These warnings were
- displayed by default until now. It is disabled by default.
+ - define_syslog_variables()
+ - import_request_variables()
+ - session_is_registered()
+ - session_register()

====================
-10. Syntax additions
+9. Extension Changes
====================
-- NOWDOC: Similar to HEREDOC, but with single quotes:
+a. Extensions no longer maintained
- <<<'LABEL' ...
+ - ext/sqlite is no longer part of the base distribution and has been moved
+ to PECL. Use sqlite3 or PDO_SQLITE instead.
- Static HEREDOCs can be used to initialize static variables and class members
- or constants:
+b. Extensions with changed behavior
- static $foo = <<<LABEL
- No variables here...
- LABEL;
+ - The MySQL extensions (ext/mysql, mysqli and PDO_MYSQL) use mysqlnd
+ as the default library now. It is still possible to use libmysql by
+ specifying a path to the configure options.
-- HEREDOC now supports wrapping the identifier with double-quotes, to complement
- the NOWDOC syntax:
+ - PDO_MYSQL: Support for linking with MySQL client libraries older
+ than 4.1 is removed.
- <<<"LABEL" ...
+ - The session extension now can hook into the file upload feature
+ in order to provide upload progress information through session
+ variables.
-- The ?: operator has been introduced:
+ - SNMP extension
+ - Functions in SNMP extension now returns FALSE on every error
+ condition including SNMP-related (no such instance, end of MIB,
+ etc). Thus, in patricular, breaks previous behavior of get/walk
+ functions returning an empty string on SNMP-related errors.
+ - Multi OID get/getnext/set queries are now supported.
+ - New constants added for use in snmp_set_oid_output_format()
+ function.
+ - Function snmp_set_valueretrieval() changed it's behavior:
+ SNMP_VALUE_OBJECT can be combined with one of
+ SNMP_VALUE_PLAIN or SNMP_VALUE_LIBRARY resulting OID value
+ changes. When no SNMP_VALUE_PLAIN or SNMP_VALUE_LIBRARY
+ is supplied with SNMP_VALUE_OBJECT, SNMP_VALUE_LIBRARY is used.
+ Prior to 5.4.0 when no SNMP_VALUE_PLAIN or SNMP_VALUE_LIBRARY
+ was supplied with SNMP_VALUE_OBJECT, SNMP_VALUE_PLAIN was used.
+ - Added feature-rich OO API (SNMP class)
+ - Dropped UCD-SNMP compatibility code. Consider upgrading to
+ net-snmp v5.3+. Net-SNMP v5.4+ is required for Windows version.
+ - In sake of adding support for IPv6 DNS name resolution of
+ remote SNMP agent (peer) is done by extension now, not by Net-SNMP
+ library anymore.
- var_dump(0 ?: 'Hello!');
+ - Date extension
+ - Setting the timezone with the TZ environment variable is no longer
+ supported, instead date.timezone and/or date_default_timezone_set()
+ have to be used.
+ - The extension will no longer guess the default timezone if none
+ is set with date.timezone and/or date_default_timezone_set().
+ Instead it will always fall back to "UTC".
-- Namespaces were added:
+ - Hash extension
+ - the output of the tiger hash family has been corrected, see
+ https://bugs.php.net/61307
- namespace my\name;
- $obj = new \my\name\MyClass;
+===========================
+10. Changes in SAPI support
+===========================
-- Dynamic access to static methods is now possible:
+- A REQUEST_TIME_FLOAT value returns a floating point number indicating the
+ time with microsecond precision. All SAPIs providing this value should be
+ returning float and not time_t.
- $foo::myFunc();
+- apache_child_terminate(), getallheaders(), apache_request_headers()
+ and apache_response_headers() are now supported on FastCGI.
-- Exceptions can now be nested:
+- The interactive shell allows a shortcut #inisetting=value to change php.ini
+ settings at run-time.
- class MyCustomException extends Exception {}
- try {
- throw new MyCustomException("Something happend", 112);
- } catch(Exception $e) {
- throw new InvalidArgumentException("You are doing it wrong!", 911, $e);
- }
+- The interactive shell now works with the shared readline extension.
-- Exceptions can now be handled in destructors.
+- The interactive shell no longer terminates on fatal errors.
-- A garbage collector has been added and is enabled by default.
+- A new PHP CLI command line option --rz <name> shows information about the
+ named Zend extension.
===================
11. Windows support
===================
-- The minimum Windows version is now Windows 2000. (Windows 98, ME and NT4 are
- no longer supported).
+- is_link now works properly for symbolic links on Windows Vista
+ or later. Earlier systems do not support symbolic links.
-- PHP Windows binaries target i586 or later. i386 and i486 are not supported.
+- As of PHP 5.4.5 and above the COM extension isn't compiled statically in PHP
+ anymore but shared. It'll still be delivered with the standard PHP release but
+ must be activated manually with the "extension = php_com_dotnet.dll" directive
+ in php.ini.
-- Support for the IIS SAPI has been dropped. Use the FastCGI SAPI instead
- (available for IIS5 and later)). FastCGI is the recommended way to use PHP
- with IIS (see http://php.iis.net/).
+- Apache 2.4 handler is supported as of PHP 5.4.9
-- A new build is available based on the latest Visual C++ Compiler (VC9).
- Its use is recommended with FastCGI or CLI. Apache's Windows binaries are not
- compatible with VC9; however, you can use Apache Lounge's build
- (http://apachelounge.com).
+==================
+12. New in PHP 5.4
+==================
-- The x64 binaries are for experimental usage only. They are not meant to be
- used in production.
+a. New Features
-- A new site is available to download Windows releases as well as Windows-only
- releases: http://windows.php.net. Windows-specific releases will be made to
- fix security issues in the bundled libraries (libpng, openssl, etc.). Please
- note that this site does not replace the main PHP site as a source of PHP
- news, resources, or documentation.
+ - A built-in CLI web server for testing purposes is now available:
+ $ php -S 127.0.0.1:8888
-- Windows support has been added for the following functions: getopt(),
- imagecolorclosesthwb(), mcrypt_create_iv(), inet_ntop(), inet_pton(),
- getmxrr(), checkdnsrr(), dns_get_record(), linkinfo(), readlink(),
- symlink(), link(), fnmatch(), stream_socket_pair(), time_nanosleep(),
- time_sleep_until(), and socket_create_pair().
+ - File Upload Progress support is implemented in the Session extension.
-- Crypt supports now all available algorithms on Windows (blowfish included).
+b. Syntax additions
-- Improved portability of stat(), touch(), filemtime(), filesize() and related
- functions (100% portable for the available data).
+ - Traits:
+ trait HelloWorld {
+ public function sayHello() {
+ echo 'Hello World!';
+ }
+ }
-- It is now possible to create hard links on Windows using the link() function,
- and symbolic links using the symlink() function. Hard links are available
- as of Windows 2000 and symbolic links as of Windows Vista.
+ class CanIGetHello {
+ use HelloWorld;
+ }
-- The PDO_OCI php_pdo_oci8.dll library (for use with Oracle version 8 client
- libraries) is no longer being built. Instead, use php_pdo_oci.dll (note no
- '8') with Oracle 10 or 11 client libraries. Connection to other database
- versions is still supported.
+ $hello = new CanIGetHello();
+ $hello->sayHello();
-- For the OCI8 extension, a new library php_oci8_11g.dll is available in
- addition to php_oci8.dll. Only one can be enabled at any time. Use
- php_oci8.dll with Oracle 10.2 client libraries. Use php_oci8_11g.dll with
- Oracle 11 client libraries. Connection to other database versions is still
- supported.
+ - Function call result array access, e.g.:
+ foo()[0]
+ $foo->bar()[0]
-- Firebird and SNMP support are no longer available on Windows. Firebird support
- may be reintroduced in the future.
+ - Callable typehint indicating argument must be callable:
+ function foo(callable $do) {
+ }
+ foo("strcmp");
+ foo(function() {});
+ $o = new ArrayObject();
+ foo(array($o, "count"));
-=====================
-11.1 New in PHP 5.3.4
-=====================
+ - Short array syntax:
+ $a = [1, 2, 3, 4];
+ $a = ['one' => 1, 'two' => 2, 'three' => 3, 'four' => 4];
+ $a = ['one' => 1, 2, 'three' => 3, 4];
-- open_basedir supports now symbolic links (checks the target).
-- is_link and SplFileInfo symbolic links related method are now fully supported
- (on Windows Vista or later).
+ - Binary number format:
+ 0b00100 0b010101
-===================

- replacement for libmysql and is recommended for all installations for
- increased performance.
+ - Class::{expr}() syntax is now supported:
