run code in 300+ PHP versions simultaneously
<?php $var = '2 + 2 = ' . (2 + 2 === 4 ? 4 : 2 + 2 === 5 ? 5 : 'dunno'); // should output "4", right? RIGHT? echo $var;

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).
