run code in 300+ PHP versions simultaneously
<?php $str_space_yes = "yes"; echo $str_space_yes == "yes" if(!($str_space_yes == "yes")) echo "!yes"; ?>

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).
