No -- this is fraught with problems in current releases of PHP (most, if not all, of which will be fixed in 4.3). Most particularly, the following caution appears at http://www.php.net/manual/en/ref.session.php: "If you are using $_SESSION and disable register_globals, do not use session_register(), session_is_registered() and session_unregister(), if your scripts shall work in PHP 4.2 and earlier." Since the default for 4.2.x is register_globals=off, this is a very pertinent warning! Even with register_globals=on, there are other problems which make it best to stick to manipulating the values in $_SESSION directly, rather than using the "equivalent" global variables. Cheers!
