I studied profilers in PHP ... Now I want to know:
What good PHP profiles can I use?
I am using XDebug and WinCacheGrind for the php profile.
Low-level profilers are modules that are loaded into the php executable, so they are harder to configure, but they provide reliable results.
PQP is a code-based profiler. Although this may not be as accurate as the low-level profilers mentioned above, this may be all you need if you are looking for some simple metrics.
XDebug? http://www.google.com/search?q=php+profiler
See my company (Semantic Designs) PHP Profiler . This does not require any changes to the PHP server.
You can use xdebug . It's also nice to note that if you use frameworks. The kohana frame has a built-in profiler that even measures your needs.
I would go for xdebug .
