run code in 300+ PHP versions simultaneously
<?php $a = "hello"; $b = "hi"; $val = "a"; echo $$val; // outputs "hello" echo "\n"; $val = "b"; echo $$val; // outputs "hi"

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).
