You don't. They timeout and are destroyed by PHP itself.

PHP will destroy sessions after they are timed out, but only if your "php.ini" file is set to do this. Often times, you will want to destroy a session before i times out (e.g. when a user logs out), in this case PHP has functions to destroy the session "session_destroy()", "session_unregister()."
