unserialize() takes a single
serialized variable (see serialize()) and converts it back
into a PHP value. The converted value is returned, and can be
an
integer, float, string,
array or object. In case the passed string is not
unserializeable, FALSE is
returned.
unserialize_callback_func directive: It's possible to set a callback-function which will be called, if an undefined class should be instantiated during unserializing. (to prevent getting an incomplete object "__PHP_Incomplete_Class".) Use your php.ini, ini_set() or .htaccess to define 'unserialize_callback_func'. Everytime an undefined class should be instantiated, it'll be called. To disable this feature just empty this setting. Also note that the directive unserialize_callback_func directive became available in PHP 4.2.0.
注: The callback parameter was added in PHP 4.2.0
If the variable being unserialized is an object, after
successfully reconstructing the object PHP will automatically
attempt to call the __wakeup() member
function (if it exists).
注: In PHP 3, methods are not preserved when unserializing a serialized object. PHP 4 removes that limitation and restores both properties and methods. Please see the Serializing Objects section of Classes and Objects or more information.
