Mike, The $GLOBALS array contains references to all variables defined in the global scope. By using the keyword global, you define a variable in the global scope (and then make it accessible through $GLOBALS).
The superglobals (eg _POST, _GET, etc) don't get this automatically, because they are "scopeless". It would only work if you used the following code beforehand: global $_POST['photo']; hth. -- Adam Goossens ======================================= Quoting [EMAIL PROTECTED]: > >When running the following code: > >foreach($GLOBALS['photo'] as $photo) > >I get: > >Warning: Invalid argument supplied for foreach() on line 63 > >Would register globals have to be on for this code to work?
