Just a quick tip regarding PHP. If you need to override the Register Globals settings in PHP and you don't have access to php.ini then you can typically add a single line to your .htaccess file (or create a .htaccess file and place it in your root web directory)

If you need to turn register_globals on use:

php_flag register_globals 1

If you need to turn register_globals off use:

php_flag register_globals 0
