I'm looking for an automated profiler for PHP that will give me a GDB-like summary of all function calls and delays caused by those calls. I've seen things like this output from DBG, but I wasn't able to get it running, and there seems to be a horribly scarce amount of "getting started" documentation for it. Their website includes very basic installation instructions, which I've peformed, but beyond that I haven't managed to figure out how to get it to actually do anything. I'm not looking for anything special, and I don't really need the other debugging functions like breakpoints/pause/etc, I just want a profiler output. Help?
