run code in 300+ PHP versions simultaneously
<?php $ar = ['a', 'b', 'a', 'c']; uasort($ar, function($a, $b){ if ($a > $b) { return 1; } if ($a < $b) { return -1; } return 0; }); print_r($ar); echo PHP_EOL; uasort($ar, function($a, $b){ return strcasecmp($a, $b); }); print_r($ar); echo PHP_EOL; uasort($ar, function($a, $b){ return strcomp($a, $b); }); print_r($ar);

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).
