<?php $arr = new ArrayIterator(array()); $regex = new RegexIterator($arr, '/^test/'); var_dump($regex->getMode(), $regex->getFlags(), $regex->getPregFlags());

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).
