defproc

I'm feeling (particularly) lazy today so I'm just going to paste from the dpDebug 2 page:

Have you ever spent time tracking down a problem with your PHP code that causes it to give unexpected results? Have you ever wished for a quick and easy way to visualise exactly what's going on, where and why? Of course you have. I have too. That's why I made dpDebug: a single-file PHP library that 'injects' a handy pop-up list of messages defined by you into any page you like. All you need to do is call the deb() function at each step you want to trace, with a brief description of what's happening and it'll be added to the dpDebug message log. You can even specify message levels (fatal, warning, notice, info, trivial, highlight or custom) and set a verbosity level to choose how much detail you want to see in the log.

Hope you like it :)
