XHProf is a profiling extension for PHP light weight enough to be run in production

XHProf is a profiling extension for PHP developed by Facebook to return sufficient profile details to diagnose problems, while still being sufficiently light weight to be run in production.

The extension itself returns nested arrays containing performance information, and is capable of storing them in a file on disk. Using a GUI can make using and interpreting the data much easier.
