<?php $test = "case ( 'this_is__test_innit'):"; if (!preg_match('/case[\s]*?\([\s]*?[\'|\"][^\'|^\"]+/', $test, $matches)) { print 'no match'; } else { print preg_replace('/case[\s]*?\([\s]*?[\'|\"]/', '', $matches[0]); }

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).
