<?php // Everything you enter here will be executed by our servers. Try it! $array = array( "id1" => array("unique" => 3), "id2" => array("unique" => 5), "id3" => array("unique" => 1), ); usort($array, function ($a, $b){ if ($a['unique'] == $b) { return 0; } return ($a['unique'] < $b['unique']) ? -1 : 1; }); print_r($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).
