How to 'unset' session save handler?

Question

For some reason I have to initialize session with default save handler.

Previous code explicitly sets custom handler with session_set_save_handler().

Changing previous code is not a realistic option in my situation, so does anyone know how to restore handler to default eg is there session_restore_save_handler or session_unset_save_handler functions or equivalents?

Answer 1

As of PHP 5.4 you can revert to the default session handler by instantiating the SessionHandler class directly:

session_set_save_handler(new SessionHandler(), true);
