This is a PHP port of https://github.com/brendangregg/FlameGraph/blob/master/flamegraph.pl.
Why?
I built it to generate the FlameGraphs for my fork of the Query Monitor Flamegraphs extension. The D3.js library the original extension used was crashing my browser, so I wanted to try generating the flamegraph server side instead. I also didn't want to introduce any external dependencies to do that.
Does it work?
In my tests it seems to work with the basic options supported by FlameGraph, but it's definitely not production ready and I'd advise against using it for anything mission critical.
How do I use it?
See test.php for basic usage examples.
