<?php $entries = []; for($i = 0; $i < 1000; $i++) { $entries[] = ['id' => $i]; } $t = microtime(true); $res = array_map(function($entry) { return $entry['id']; }, $entries); $t = microtime(true) - $t; echo number_format($t, 4) .

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).
