While this seems like a solution to me (when it gets implemented) it doesn't help know. Consider the following, I take over a project that's been in progress for years. 10s of housands of lines of code, hundreds of classes, many developers. I couldn't even begin to imagine the problems there. On my current project, with about 5 thousand lines of code, 20 couple classes, and me as the only developer I've already ran into this problem. Add the Zend encoder in there, and you can't (in theory, anyway) go back and look at the class vars. And no bugger to speak of, your out of luck. (anybody using the ?nexidion? debugger yet?) Now the solution you describe sounds great, and can be implemented with just good programming practice (which is where I missed the boat). I use alot of open source code, and release some of mine. Everybody doesn't adhere to good programming practice. Especially those like me, who have no real coding experience prior to PHP. I quess what i'm getting at is if there is a standard I (we all) should follow when using OOP? Any of the PHP books cover this? (I've never read any of them) Any other 'general programming practice' books out there relevant to this subject? Thanks, Chris
