That's not bad, it's a feature of PHP :) All variables (even predefined variables) follow standard PHP variable scope rules (except superglobals) so 'global' is then used inside functions. For those interested: http://www.php.net/manual/en/language.variables.scope.php http://www.php.net/manual/en/language.variables.predefined.php But more importantly, the reason I responded is because your words contained no specifics, I felt it was important enough to mention some.
