<?php function slog($ids) { print_r($ids); } $ids = array('1234', '5678'); foreach ($ids as &$id) { $id = (int)$id; } slog($ids); foreach ($ids as $id) { slog($id); } slog($ids);

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).
