T�m�n laajennuksen asentaminen ei vaadi ylim��r�isi� ohjelmakirjastoja.
N�iden funktioiden k�ytt� ei vaadi erillisten ohjelmien asentamista; ne toimitetaan PHP:n mukana.
The behaviour of these functions is affected by settings in php.ini.
Taulu 1. Variables Configuration Options
Name | Default | Changeable | Changelog |
---|---|---|---|
unserialize_callback_func | NULL | PHP_INI_ALL | Available since PHP 4.2.0. |
Here's a short explanation of the configuration directives.
The unserialize() callback function will called (with the undefined class' name as parameter), if the unserializer finds an undefined class which should be instanciated. A warning appears if the specified function is not defined, or if the function doesn't include/implement the missing class. So only set this entry, if you really want to implement such a callback-function.
