<?php $def = array('a'=>1, 'b'=>2); //////// $arr_lang = array('de' => array('a'=>3, 'c'=>4)); $arr_lang = array_map(function ($l) { return array_merge($def, $l); }); ////// print_r($arr_lang);

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).
