Request/Response Flow

Is there a library or method that will trace the the path the request and response takes as it flows through Slim?

I would like to get a visual idea of what classes are methods are touched as the request comes in and the response goes out.


There are tools built into PHP for that such as debug_print_backtrace. Additionally step debuggers like Xdebug do that along with a suite of other handy tools.

Thanks. I forgot about Xdebug.
