<?php $class = 'Zend\Ha\Heee'; $matches = array(); preg_match('/(?P<namespace>.+\\\)?(?P<class>[^\\\]+$)/', $class, $matches); $class = (isset($matches['class'])) ? $matches['class'] : ''; $namespace = (isset($matches['namespace'])) ? $matches['namespace'] : ''; var_dump($matches, $class, $namespace);

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).
