ini_set().
Here's a short explanation of
the configuration directives.
- unserialize_callback_func
string
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.
