You may also apply the same concept explained by Jessica when user login insert a time from time(); function in the database. And when you check for user login or not put this code of script. $inactive = 300; // for 5 minute $current_time = time(); $prev_time = /*select prev time from the database*/ $session_life = $current_time - $prev_time; if($session_life > $inactive) { unset($_SESSION[$user]); } else { $sql="update $table set $field_name = $current_time"; } i hope this will be helpfull for you
