session_module_name — Get and/or set the current session module

Description

session_module_name ([ string|null $module = NULL ] ) : string|false

session_module_name() gets the name of the current session module, which is also known as session.save_handler.

Parameters

module

If module is specified and not NULL, that module will be used instead. Passing "user" to this parameter is forbidden. Instead session_set_save_handler() has to be called to set a user defined session handler.
