PHP 5.3.x 中弃用的功能

PHP 5.3.0 新增了两个错误等级: E_DEPRECATED 和 E_USER_DEPRECATED. 错误等级 E_DEPRECATED 被用来说明一个函数或者功能已经被弃用. E_USER_DEPRECATED 等级目的在于表明用户代码中的弃用功能, 类似于 E_USER_ERROR 和 E_USER_WARNING 等级.

下面是被弃用的 INI 指令列表. 使用下面任何指令都将导致 E_DEPRECATED 错误.

弃用函数:

call_user_method() (使用 call_user_func() 替代)
call_user_method_array() (使用 call_user_func_array() 替代)
define_syslog_variables()
dl()
ereg() (使用 preg_match() 替代)
ereg_replace() (使用 preg_replace() 替代)
eregi() (使用 preg_match() 配合 'i' 修正符替代)
eregi_replace() (使用 preg_replace() 配合 'i' 修正符替代)
set_magic_quotes_runtime() 以及它的别名函数 magic_quotes_runtime()
session_register() (使用 $_SESSION 超全部变量替代)
session_unregister() (使用 $_SESSION 超全部变量替代)
session_is_registered() (使用 $_SESSION 超全部变量替代)
set_socket_blocking() (使用 stream_set_blocking() 替代)
split() (使用 preg_split() 替代)
spliti() (使用 preg_split() 配合 'i' 修正符替代)
sql_regcase()
mysql_db_query() (使用 mysql_select_db() 和 mysql_query() 替代)
mysql_escape_string() (使用 mysql_real_escape_string() 替代)
废弃以字符串传递区域设置名称. 使用 LC_* 系列常量替代.
mktime() 的 is_dst 参数. 使用新的时区处理函数替代.

弃用的功能:

弃用通过引用分配 new 的返回值.
调用时传递引用被弃用.

Correction on my previous note. sed -i 's/\$HTTP_$.*$_VARS/\$_\1/g' {} \; will screw up multiple instances of $HTTP_*_VARS in the file. You'll have to use an instance of sed like: sed -i 's/\$HTTP_SERVER_VARS/\$_SERVER/g' i.e. find ./ -name "*.php" -exec sed -i 's/\$HTTP_POST_VARS/\$_POST/g' {} \; find ./ -name "*.php" -exec sed -i 's/\$HTTP_GET_VARS/\$_GET/g' {} \; ... for each of the deprecated variables you might have in your files. It also occurred to me a simple php conversion script would also work: $search=array( "/HTTP_SERVER_VARS/", "/HTTP_POST_VARS/", "/HTTP_ENV_VARS/", "/HTTP_GET_VARS/", "/HTTP_COOKIE_VARS/", "/HTTP_SESSION_VARS/", "/HTTP_POST_FILES/"); $replace=array( "_SERVER", "_POST", "_ENV", "_GET", "_COOKIES", "_SESSION","_FILES"); $content=file_get_contents("somefile.php"); $content=preg_replace($search,$replace,$content); file_put_contents("somefile.php",$content); add directory recursion functions, ect.

If you previously defined register_long_arrays in php.ini and have a lot of code with $HTTP_*_VARS that need to be replaced the following may help on *.nix systems: sed -i 's/\$HTTP_$.*$_VARS/\$_\1/g' filename.php What this command does is replace all occurrences of $HTTP_*_VARS with their respective $_ counter parts, e.g. $HTTP_COOKIES_VAR to $_COOKIES To replace alot of files, you might combine it with the find command: find ./ -name "*.php" -exec sed -i 's/\$HTTP_$.*$_VARS/\$_\1/g' {} \; For other deprecated variables like $HTTP_POST_FILES change your sed arguments: sed -i 's/\$HTTP_POST_FILES/\$_FILES/g' Deprecated variables created by the register_long_arrays directive as far as I know are: $_POST $_GET $_SERVER $_ENV $_COOKIE $_SESSION

A backward compatibility break which is not documented: Fatal error: Uncaught exception 'RuntimeException' with message 'Directory name must not be empty.' This happens with new RecursiveIteratorIterator( new RecursiveDirectoryIterator( $staticPath ) )
