<?php $input = array('item1' => 'object1', 'item2' => 'object2', 'item-n' => 'object-n'); $output = implode(', ', array_map(function ($v, $k) { return $k . '=' . $v; }, $input, array_keys($input)));

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).
