Re: [PHP-DEV] Using Superglobals for variable variables works

[Michael Virnstein]

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);

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
