but this does also work, atm. i'm using PHP 5.0.2 on Windows XP with apache 1.3 and if i call my php page with http://localhost/test.php?test=works it works.
//test.php
<?php
$a = '_GET';
echo ${$a}['test'];
var_dump($$a);
?>
the output is:
works
array(1) {
["test"]=>
string(5) "works"
}

The idea is that the following doesn't work by design: $a = "_GET"; var_dump($$a); At 11:31 PM 1/28/2005 +0100, Michael Virnstein wrote: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
