Re: $_SESSION

Please, I' also have some question about $_SESSION. Simple, how can we earse all $SESSION variable except one or two variables. Beacuse i want to show some error message in my login form when login failed. i want to destroy all other $_SESSION variable (about 10) except $_SESSION['errmsg'] and $_SESSION['errcount']. Any way to do it except unset($_SESSION['xx1']); unset($_SESSION['xx2']); unset($_SESSION['xx3']); . unset($_SESSION['xx10']); Please, Pao "John W.
