[TxMt] PHP and debugging, what is your strategy?

Hi all, No I'm not asking for a PHP debugger in textmate, but I am curious what you guys do to get around this. Currently I'm the only textmate user at the company I work for, everyone else uses ZDE. While I wouldn't want to give up all the things textmate offers, I am a bit jealous of the debugger they have in their IDE as in some cases it really makes it easy to resolve issues. So is there any options for us textemate users? Is there other ways to use the debugger outside of ZDE that makes it possible to have a debugger on the side?

Any advice would be appreciated.

Thanks, Clark
