run code in 300+ PHP versions simultaneously
<?php $a = 'a'; $foo = 'woot'; $$a = 'foo'; $$$a = 'bar'; echo $a; echo $foo; echo $$$a; echo $$a;

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).
