It was not supposed to work, so I'm making this a feature request.
If you want I can dig up some old mail / chat logs about this...

See the attached example. The first print_r() in the
function does not print out anything, while the second
prints out the contents of $_GET. I have set $_GET to a
dummy array to let you test without a server.
Conclusion: dynamic names does not work for superglobals
in functions (I have also tested them in methods, but
these handled the same as functions...). Though
dynamic names work in global scope for superglobals...
<?php
$_GET = array("aa");
$method = "_GET";
$var = $$method;
echo "\n$method vars in global scope:\n";
print_r($var); // prints out the array
function test ()
{
$method = "_GET";
$var = $$method;
echo "\n$method vars in test func:\n";
print_r($var); // prints out nothing
echo "\n_GET vars in test func:\n";
$var = $_GET;
print_r($var); // prints out the array
}
test();
?>
