Here is a short explanation of the configuration directives.
-
unserialize_callback_func string
-
The unserialize callback function will called (with the undefind 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.
