Hey, #PHP friends - what's the *easiest* way to compare the speed & memory use of two different functions?

The functions themselves are quite simple (a dozen or so lines) so I can't really be bothered to set up a whole XDebug environment.

Is there an online tool which will give me a rough answer?

If they're not enough then really Xdebug + an analyser such as KCacheGrind are the way to go.

https://3v4l.org/ allows you to run code online but I don't think it would help with profiling.
