 ====== PHP 5.3 upgrading notes ====== ====== PHP 5.3 upgrading notes ======
-  * This document is work in progress, and eventually will live in the PHP Manual +  * This document has been removed in favor of [[http://cvs.php.net/viewvc.cgi/php-src/UPGRADING?view=markup&pathrev=PHP_5_3|UPGRADING]] and will eventually live in the PHP Manual (see below) 
-  * Add all information, changed behaviour or new features, much like [[http://php.net/migration52]] is for 5.2.0 +  * The 5.3.0 upgrade guide can be seen here: [[http://docs.php.net/migration53]] 
-  * See also [[doc:todo:undocumented]]+  * The 5.2.0 upgrade guide can be seen here: [[http://docs.php.net/migration52]] 
 +  * The 5.1.0 upgrade guide can be seen here: [[http://docs.php.net/migration51]]
  
- 
-===== Changes to the syntax which might break existing applications ===== 
- 
-  * [[http://doc.php.net/namespace|namespace]] is now a reserved word. Applications can't use //namespace// as identifier anymore. Doing so will create a Fatal Error while parsing the script. 
-  * //goto// is now a reserved keyword. Applications can't use //goto// as identifier anymore. Doing so will create a Fatal Error while parsing the script. 
-  * //Closure// is now a reserved class. (Used by lambda and closure) 
- 
-===== Changes to functions affecting backwards compatibility ===== 
- 
-  * The functions natsort, natcasesort, usort, uasort, uksort, array_flip, array_unique don't take objects anymore as parameters. For accessing their properties using this way you have to cast the objects to arrays first. 
-  * var_dump() output with objects (some internal classes emit internal states as private properties that are not accessible otherwise, for Example SimpleXML exposes its virtual properties) 
-  * session_start() now returns false if session startup fails for some reason. 
-  * clearstatcache() now defaults to not clear the realpath cache. 
-  * opendir(), scandir() and dir() now use the default context if no context passed. 
-  * If a function with by-reference parameters is called by value ( for example with [[http://php.net/call_user_func_array|call_user_func_array]]) a warning message is produced and all by-reference parameters are set to NULL. In older versions, the function was called with by value parameters. 
-  * call_user_func now propagates $this even if the callee is the parent class (cf #47402) 
-  * The new mysqlnd library necessitates using [[http://dev.mysql.com/doc/refman/5.0/en/password-hashing.html|MySQL's newer 41 byte password format]]. Continued use of the old 16 byte passwords will cause mysql_connect() to produce the following error message: "mysqlnd cannot connect to MySQL 4.1+ using old authentication." 
- 
-===== Changes to method signatures affecting backwards compatibility ===== 
- 
-  * %%__get, __set, __isset, __unset, __call%% magic methods should be public now and can not be static, argument signatures enforced 
-  * %%__toString%% magic method can not accept parameters 
-  * %%__callStatic%% is a new magic method 
-  * %%count() vs count_elements%% handler resolution rules change (might break custom PHP exts not in PECL/php-src) 
-  * %%__invoke%% %%('class fail { function __invoke() { echo "hello world\n"; } } $o = new fail; $o();' // hello world)%% 
- 
- 
-===== Changes to binary releases for Windows ===== 
- 
-  * The minimum Windows versions are now windows 2000/XP (windows 98, ME or NT4 are not supported anymore) 
-  * Binaries target 586 or later, i386, i486 are not supported (was already the case before but not mentioned in the manual) 
- 
-===== Libraries added ===== 
-  * mysqlnd (optional replacement for libmysql) 
- 
-===== Extensions added ===== 
-  * [[http://docs.php.net/fileinfo|Fileinfo]] 
-  * [[http://docs.php.net/intl|Intl]] 
-  * [[http://docs.php.net/phar|Phar]] 
-  * [[http://docs.php.net/sqlite3|SQLite3]] 
- 
-===== Extensions removed ===== 
-==== Moved to PECL and maintained there ==== 
-  * ncurses (maintained) 
-  * fpdf (maintained) 
-  * dbase 
-  * fbsql 
-  * ming 
-  * msql 
- 
-==== Not maintained and superseded  ==== 
-  * sybase (please use sybase_ct which is maintained and still in core) 
- 
-===== Extension Changes Causing Incompatibilities ===== 
- 
-==== OCI8  ==== 
-  * Oci_close() on a persistent connection, or all variables referencing a persistent connection going out of scope, now rolls back any uncommitted transaction.  Make sure you explicitly commit or rollback as needed.  Alternatively, setting oci8.old_oci_close_semantics to On gives the old behavior where oci_close() is a no-op for all types of connection. 
- 
-==== Session  ==== 
-  * Sessions would no longer succeed to store session-files in "/tmp" path if open_basedir restriction is enabled, and "/tmp" is not explicitly added to allowed paths list (special treatment of "/tmp" was added in 5.2.2, but was not documented) 
-===== Deprecated  ===== 
-  * Ticks (declare(ticks=N) and [[http://docs.php.net/register-tick-function|register_tick_function()]] now issues ''E_DEPRECATED'') 
-  * define_syslog_variables() now issues ''E_DEPRECATED'' 
-  * all ereg functions now issues ''E_DEPRECATED'' (note that not all of them are prefixed with ereg) 
-  * Deprecated features (safe_mode, register_globals, register_long_arrays, magic_quotes_gpc, magic_quotes_sybase & magic_quotes_runtime) will now issue an ''E_DEPRECATED'' if its turned on at startup 
-  * zend.ze1_compatibility_mode will now issue an ''E_WARNING'' if its turned on at startup 
- 
-===== Undeprecated ===== 
-  * [[http://docs.php.net/is-a|is_a()]] ([[http://docs.php.net/manual/en/language.operators.type.php|this page]] says "[...] but is_a() has since been deprecated in favor of instanceof.") 
- 
-===== Changes to .INI settings ===== 
-  * Removed zend.ze1_compatibility_mode. 
-  * user_ini.filename user-initialization mechanism and config variables: user_ini.filename and user_ini.cache_ttl. 
-  * Added support for special [PATH=/opt/httpd/www.example.com/] and [HOST=www.example.com] sections. Directives set in these sections can not be overridden by user-defined ini-files or during runtime. 
-  * Added mbstring.http_output_conv_mimetype that specifies the regex pattern of content types for which mb_output_handler() is activated. 
-  * Allowed using full path to load modules using "extension" directive. 
-  * Allowed "ini-variables" to be used almost everywhere ini php.ini files. 
-  * Allowed using alphanumeric/variable indexes in "array" ini options. 
-  * Allowed run-time tightening of open_basedir (http://docs.php.net/manual/en/ini.sect.safe-mode.php#ini.open-basedir)
