run code in 300+ PHP versions simultaneously
<?php $foo = "baz"; $bar = "foo"; if(isset($lol['baz'][$bar])) { var_dump($foo); } else { var_dump($bar); } ?>

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).
