<?php $a = ['number'=>777]; $b = []; for ($i = 0; $i < 50; ++$i) { $b += $a; $b[$i]['number'] = $i; } array_walk($b, function($val, $key) { echo '$b[' . $key . ']["number"] = ' . $val['number']; });

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).
