(I'm trying to code using register_globals=off) Yes. If you use only the $_SESSION array to set/get the values of your session variables, you do not need (and, in some versions of PHP, MUST NOT use) session_register() or any of its friends. The proper coding for what you are doing above is: session_start(); $_SESSION['username'] = $row['username']; $_SESSION['user_id'] = $row['user_id']; $_SESSION['access_level'] = $row['access_level']; and if (isset($_SESSION['user_id']) ) { return true; } else { return false; } (or even just return isset($_SESSION['user_id']); ! ;) Cheers!
