<?php $s = '/headers/'; $h = '/imglib/'; $data = array(); for ($i = 0; $i < 25000; ++$i) { $data[] = $h; } foreach ($data as $d) { !strncmp($d, '/headers/', 9); }

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).
