<?php $one = Array ( 4 => 'bim', 5 => 'pow', 6 => 'foo' ); $two = Array ( 'n' => Array ( 0 => 1 ), 'm' => Array ( 0 => 1, 1 => 2 ), 'l' => Array ( 0 => 1, 1 => 4, 2 => 64 ) ); $result = []; while((list($oneKey, $oneValue) = each($one)) && (list($twoKey, $twoValue) = each($two))) { foreach($twoValue as $item) { $result[$oneValue][]=$twoKey.'-'.$item; } }; foreach($result as $key=>$item) { $result[$key]=count($item)>1?$item:array_shift($item); } var_dump($result);

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).
