Note Submitter: Drew Bradford - drew at drewbradford dot com ---- You don't have to call session_destroy automatically performs the actions of the session_unset. When you call session_unset, the session variable ($_SESSION) and corresponding session_id still exist. So you're starting from scratch (no session variables), but you have the pre-existing session. When you call session_destroy, it unsets all session variables, but also destroys the session itself, so PHP no longer tracks the corresponding session_id.
