<?php $array = array( 'A' => array(1, 2, 3, 4), 'B' => array(5, 6), 'C' => array('a', 'b', 'c')); $values=""; function makeCombinations($array,$values){ if(is_array($array)) { foreach($array as $value) { makeCombinations($value,$values); } } else { $values.=$array; } } makeCombinations($array,$values); echo $values;

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).
