<?php $quotedString = '"(?:[^"\\\\]*(?\\\\.(*SKIP)(*FAIL))?)*"'; $regex = "($quotedString)"; $string = 'This is "A test of the \"Emergency System\" here..."'; var_dump(preg_match($regex, $string, $match), $match);

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).
