DUPLICATE
I've reported this bug before. Bug #15730.

The strange thing is that it works in global scope, but not in function
scope. I quess people will try to use this for similar thing such as
$var = "HTTP_" . $method . "_VARS";
global $$var;
$form = $$var;
or
$form = $GLOBALS["HTTP_" . $method . "_VARS"];
But using
$form = ${"_$method"};
is much more simple, and requires no globals...
This is inconsistent as it works outside of functions
but not inside of functions, although we advertise
the superglobals, as they behave the same inside
or outside any scope... I hit this 'bug' because I wanted
to use exactly this short thing...

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();
?>
