<?php preg_match_all("/(?J)((?<A>a)!|(?<A>a)=(?<type>[si])) ((?<B>b)!|(?<B>b)=(?<type>[si]))/", "a! b=s a=i b!", $m, PREG_SET_ORDER); print_r($m);

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).
