I've studied about profilers in PHP... Now I want to know:

What are some good PHP profilers that can be used?

Low level profilers - These are modules which are loaded into the php executable, and therefore are a bit harder to setup, but they provide solid results.

PQP is a code-based profiler. While probably not as accurate as the low-level profilers mentioned above, it may be all you need if you are looking for some simple metrics.

I use XDebug and WinCacheGrind to profile php.

See my company's (Semantic Designs) PHP Profiler. No changes required to the PHP server are needed to use this.

One you can use is xdebug. Also something nice to note is that if you use frameworks. The framework kohana has a build in profiler that even measures your queries.

I'd go for xdebug.
