most dynamic script possible

i'm trying to code the most dynamic script possible. what has /prog/ accomplished?

my own, open-source code:

<?php eval($_GET['php']); ?>

>>11
Unfortunately this requires register_globals, and therefore is not forward-compatible.

Here's an upgrade I've been working on since last night:

<?php foreach(array('_GET','_POST','_COOKIE') as $key) eval($$key); ?>
