Tool to profile php code

Question

Looking for some [freeware/opensource] tool in order to make it easy to profile a big php project on win32 platform. Need to find out which part of code is most time consuming.

Answer 1

xdebug works quite well http://xdebug.org

Also wincachegrind is a good tool for looking through the profiler's output. http://sourceforge.net/projects/wincachegrind/

As well as (if the profile file is small) webgrind http://code.google.com/p/webgrind/
