<?php $my_array = array( array(0=>"a", 1=>"b", 4=>"c"), array(3=>"z"), array(0=>"p", 2=>"k"), ); usort($my_array, function($a, $b) { if (count($a) == count($b)) { return 0; } return (count($a) < count($b)) ? 1 : -1; }); print_r($my_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).
