If you're being academic about it please remember that the way PHP defines globals is different to most other languages. PHP: A variable defined at the top-level scope. World: A variable that is visible at every scope. This is an important difference if you ever move from PHP to another language. It ultimately also means that only the superglobals are true globals. The $GLOBALS superglobal contains all variables defined at the top-level scope, including $GLOBALS, so $GLOBALS['GLOBALS']['GLOBALS']['GLOBALS']['_SERVER'] is a perfectly valid, if daft, way of accessing $_SERVER. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
