I have a session variable called $_SESSION['total'] the problem is I can't delete/reset it. I have tried $_SESSION['total']= 0; $_SESSION['total']= "";
I guess you didn't know/think of trying null: $_SESSION['total'] = null; ...which has the same effect as using: unset($_SESSION['total']); // as you have been told on at least 3 diff occasions ;-)

Not true. If you set it to null, it still exists...it's just null. If you unset it, the variable no longer exists. $_SESSION['total'] = null; if ( isset ( $_SESSION['total'] ) ) { echo ( "Yes" ); } else { echo ( "No" ); } unset ( $_SESSION['total'] ); if ( isset ( $_SESSION['total'] ) ) { echo ( "Yes" ); } else { echo ( "No" ); } -- John C.
