PHP Bug Type:     Scripting Engine problem
Bug description:  Can't set/unset global-ed variables

I'm running the following script:

$id=1;
function test()
{
	global $id;
	unset($id);
}
test();
echo($id);

As the function test is being executed I think, the $id variable should be
unset and so the script should output nothing, but it outputs 1. It IS
possible to change the value od $id inside the 'test' function, it's just
not possible to change the set/unset state. 
It's easy to omit the problem by unsetting $GLOBALS["id"] variable, but I
think it should be possible to unset the global-ed variable in both ways.
The problem affects all PHP 4.x versions. The 3.x versions work as I
expect.

Regards,
Marek Matula
