Superglobals blues

[Dalibor Karlovic]

I need to access exaclty one of the superglobals arrays and don't want to
use $_REQUEST. Having the name of the form method used on submit in
$this->sMethod and the name of the feild submited in $sName, I've tried

${'$_'. strtoupper($this->sMethod)}[$sName]

but it doesn't work. Writting a form generation/validation class, that is
why I need this. If somebody has an idea...

I've found that accessing superglobals like this won't work (which is true
:) and that they need to be referenced. How?

TIA

$sMethod='_POST';
$aData = &$$sMethod;
var_dump($aData);

In a relugar script it prints out content od $_POST, but inside a class it
prints out NULL. The exact same code. What am I missing here?

This works, but superglobals are supposed to be globally accessible without
global. I'm confused :) But anyway, thank you very much.

i think ..
when script is compiled the variable and its range are setup and
there are set as local, even _POST,
_POST, becouse it's built after compilation, it is local too

if i'm wrong - correct me, please..
