The idea is that the following doesn't work by design:
$a = "_GET";
var_dump($$a);

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 -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
