PHP Profiler with method execution count, times etc. without extensions

问题

Is there any class or library that I can use for profiling, finding bottlenecks, seeing unnecessary execution times etc in my local php environment using beside the CI's default profiler?

I'm going to use it remotely and my host doesn't have any debug extensions installed, and I don't want to ask them to install, and if there's any PHP solution of it, it'll be nice.

If possible, without installing an extension or altering php.ini file please.

(I edited the title because it made the question look Codeigniter specific, but it's not.)
