I'm currently using PHP 4.1.1. If I decide to upgrade to 4.3 will I encounted any issues, ..especially with phpMyAdmin 2.2.3, or will I need to upgrade that as well? Thanks
the main issue you might face is that fact that in PHP 4.2.0 and later, the default value for the PHP directive register_globals is off. this will cause scripts that access global GET/POST variables to break.
