<?php
$x = '_GET';
print_r($$x);
?>

it not possible to access superglobals with this type dynamic vars.

because they are super-globals, not globals. so they are in no namespace hash table?

I think this should be commentet.

Seems to be a duplicate of
http://bugs.php.net/bug.php?id=15479

I also reported a bug with this, and it contained
much more info (like this WORKED in global scope
with the version I was using). I am said, I cannot find that bug now...

This was discussed in the lists but I can't find these discussions :/  iirc, Derick mentioned why it doesn't work but I don't remember what was said exactly or if a final conclusion was made.  Maybe this behavior will change?
