Subject: Using Superglobals for variable variables works
From: michael.virnstein@web.de (Michael Virnstein)

Hi PHP-Devs,

i don't know if it is a bug or a new feature of php5. The php manual 
says, that using superglobals for variable variables isn't working, so 
something like this shouldn't work:

<?php

$a = 'hello world';

echo ${$_GET['test']};

?>

Actually it does work. Is this intended now? Would be nice, but if it is 
a simple bug and i can't rely on it to work in the future, i won't use 
it. Hope it is a feature though. ;)

Regards, Michael
