run code in 300+ PHP versions simultaneously
<?php $array = []; // make some array for testing for($i=0; $i < 100; $i++) $array["key$i"] = $i; for($i=0; $i < 1000000; $i++) { reset($array); $firstKey = key($array); }

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).
