PHP Debugger

I don't know if any work has been done on this, if it's BEING worked on, or if its just completely silly, but what are the possibilities behind a PHP Debugger? At least at a level that would do things like perl -cw <script> to start with? I know there's been a few times where I could have used some intuitive debugging, and a friend who is the lead developer a rather influential company currently using mod_perl has told me the biggest reason they don't switch to PHP is because of the lack of a decent debugger for him to work with. I kind of see a decent debugging suite as an essential part of a good programming package - is there a possibility of starting to look at something like this? -Brendan ----- Brendan W. McAdams | ph.
