<?php $re = '/\b(\d+(?:\.\d+)?)mcg\b/'; $str = 'some text 0.25mcg some more text some text 25mcg some more text'; preg_match_all($re, $str, $matches); print_r($matches[1]);

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).
