<?php $course_id = "SW_3200R50S14C"; preg_match("/[A-Za-z]+/",$course_id, $matches); print_r($matches); preg_match("/[0-9]+/",$course_id, $matches); print_r($matches); preg_match("/R[0-9]+/",$course_id, $matches); print_r($matches);

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).
Note: hhvm uses a JIT which only kicks in after a few runs. Since we run scripts only once, hhvm always runs slower.
