The newer internal parameter parsing API has been applied across all the extensions bundled with PHP 5.3.x. This parameter parsing API causes functions to return NULL when passed incompatible parameters. There are some exceptions to this rule, such as the get_class() function, which will continue to return FALSE on error.

在PHP5.3.x的所有绑定扩展中应用了新的内部参数解析API，当给函数传递了不兼容的参数时将返回NULL.但有一些例外，比如函数get_class在出现错误时将会返回FALSE。

The array functions natsort(), natcasesort(), usort(), uasort(), uksort(), array_flip(), and array_unique() no longer accept objects passed as arguments. To apply these functions to an object, cast the object to an array first.

数组函数natsort(), natcasesort(), usort(), uasort(), uksort(), array_flip(), 和 array_unique()将不再接受对象做为参数，在将这些函数应用于对象时，请首先将对象转换为数组。

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.

The new mysqlnd library necessitates the use of MySQL 4.1's newer 41-byte password format. Continued use of the old 16-byte passwords will cause mysql_connect() and similar functions to emit the error, "mysqlnd cannot connect to MySQL 4.1+ using old authentication."

新的mysqlnd类要求使用比MySQL4.1新的41位的密码格式。使用旧的16位的密码将会导致mysql_connect和类似的函数产生错误，"mysqlnd不能使用旧的认证连接Mysql4.1及以上的版本"。
