PHP 4.0 Bug #2674 Updated: unset() does noet work inside function

ID: 2674 Updated by: zeev Reported By: gert@wins.uva.nl Status: Closed Bug Type: Scripting Engine problem Assigned To: Comments: This is a known incompatibility with PHP 3.0, that is consistent with the way PHP 4.0 works. In PHP 4.0, when you write 'global $foo;' you basically hint PHP to create a reference to the global variable $foo, with the local name $foo. When you later on call unset($foo), PHP disallocates the local reference, and not the global variable that reference points to. You can unset global variables by using the special $GLOBALS array: unset($GLOBALS["foo"]); should work. Full Bug description available at: http://bugs.php.net/version4/?id=2674
