run code in 300+ PHP versions simultaneously
<?php $width = 5; foreach (range(1, $width) as $i) { printf("%{$width}s\n", join(array_reverse(range(1, $i)))); } $width = 5; foreach (range(1, $width)) { printf("%{$width}s\n", join(range(1, $i))); }

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).
