If you can show me a debugger that will work on a PHP application in the Symfony framework, runs on Mac, and is not built on Eclipse or a similar lumbering monstrosity, I will gladly give it a try. (Hell, I tried PHPStorm, but it's just so painful to use...) Until and unless such a thing appears, debug logging is pretty much what I've got. (And given the complexity of the project in question, and the fact that I'm basically its only developer, debug logging is still pretty vital for running down the bugs the users run into in production. Good thing it's just a free hobby project!)
