run code in 300+ PHP versions simultaneously
<?php $DATA = '_GET'; var_dump(${$DATA}); function test() { global $_GET; $DATA = '_GET'; var_dump(${$DATA}); } test();

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
