Description:
------------
I think that this is a bug, see the code, it is self-explaining :-)

Reproduce code:
---------------
function xx ($type = '_POST') {
    echo '<pre>'; print_r($$type); echo '</pre>';
}

xx();


Expected result:
----------------
I expect to see my $_POST variables! :-)

Actual result:
--------------
Notice:  Undefined variable:  _POST in /www/album.cz/www/album/registrace/index.php on line 31

wtf php?
 [2003-07-08 15:53 UTC] spaze at exploited dot cz 
workaround - this way it works, but..

function foo($type='_GET') {
	global $$type;  // note this
	print_r($$type);
}

looks like a "superglobal access" problem?

You can't access super-globals via variable-variables.
