RE: [PHP-GENERAL] Classes, objects, and a huge problem!

Make sure that you are not confusing a class and an instance. I believe the session saves the instance data across pages, but I think it is up to you to make sure the class is there on each page where instances of the class are used. > -----Original Message----- > From: Szii [mailto:szii@earthlink.net] > Sent: Sunday, June 11, 2000 9:11 PM > To: php-general@lists.php.net > Subject: [PHP-GENERAL] Classes, objects, and a huge problem! > > > Okay, after MUCH testing here's what's up with registered values > and sessions... > > If you start a session and register a CLASS you're fine.
