This allows you to get a nice view of what takes time in your application - and it sometimes definitly helps to locate the function that is slowing everything down ^^ (With KCacheGrind, I mean WinCacheGrind is not as good as KCacheGrind.) You'll get exactly the same kind of thing with PHP scripts -) This screenshot is from a C++ program in KcacheGrind : (Read the documentation for more informations) Xdebug.profiler_output_name = files_names Xdebug.profiler_output_dir = /tmp/ouput_directory Xdebug.profiler_enable_trigger = 1 Profiling activated when requested by the GET parameter The profiling-related part of my php.ini looks like this : xdebug.profiler_enable = 0 Profiling not activated by default What I generally do is not enable the profiler by default (it generates quite big files, and slows things down), but use the possibility to send a parameter called XDEBUG_PROFILE as GET data, to activate profiling just for the page I need.

To get profiling files, you have to install and configure Xdebug take a look at the Profiling PHP Scripts page of the documentation. KCacheGrind probably only Linux and linux-like That's the one I prefer, btw.Webgrind web interface should work on any Apache+PHP server.

Software that read the profiling data, and presents you something readable.The Xdebug extension, to generate profiling data for the script.The other solution, that works quite nice if you want to identify which function takes lots of time in an entire script, is to use : Not perfect, but useful, and it doesn't take much time to set up. Something like this, so, if you want to know how long it take to serialize an array : $before = microtime(true) Įcho ($after-$before)/$i.

This is a nice solution if you want to benchmark a couple of instructions like compare two types of functions, for instance - it's better if done thousands of times, to make sure any 'perturbating element' is averaged. The quite 'naïve' one is using microtime(true) tobefore and after a portion of code, to get how much time has passed during its execution other answers said that and gave examples already, so I won't say much more.
