Is there php benchmarking tool like chrome's timeline

Question

Open google chrome, browsing your favorite website, then right click > open inspect element, and go to timeline tab, you can record timeline rendered by google chrome.

Is there any php benchmarking tool to retrieve information, get timeline of functions, and variables rendered by webserver?

Thanks.

Answer 1

most known tool is Xdebug.
However, manual code profiling (that's that this thing is called) is no less effective. Just put a few microtime(1) calls into code, analyze output and move them accordingly
