<?php $array1 = [ ['id_cat' => 1, 'title_cat' => 2], ['id_cat' => 3, 'title_cat' => 4] ]; $array2 = [ ['id_prod' => 1, 'title_prod' => 2], ['id_prod' => 3, 'title_prod' => 4] ]; foreach($array1 as $key => $value) { $result[$key] = array_merge($array1[$key], $array2[$key]); } echo json_encode($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).
