run code in 300+ PHP versions simultaneously
<?php $a = $b = array_fill(0, 500, 'sucks'); $t = microtime(true); $c = array_reverse($a); while($c) { array_pop($c); } var_dump(microtime(true) - $t); $t = microtime(true); while($b) { array_shift($b); } var_dump(microtime(true) - $t);

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).
