Does a PHP per-function (or per-task) performance / benchmark reference exist?

Question

I'm running my own (albeit, basic) benchmarks in a linux-based sandbox. However, I'd love to find a per-function or per-task performance / benchmark reference or utility for comparison.

Does this exist?

Of course I've done my own fair diligence / searching and have so far come up empty handed..

(I'm primarily interested in information relevant to PHP 5.3)

Thanks very much! :)

You can use a profiler to evaluate which function calls are more costly.

XDebug can also provide log files that you can later load into KCacheGrind to get a nice tree output of what time was spent where in your code.
