I agree that PHP is good for starting learning web development and for small sample apps, but from experience I really think that large-scale PHP applications are not easy to manage. The codebase becomes disorganized very quickly, and tracking down a piece of code's "hierarchy" (what it inherits from, what methods it has available, etc.) can be a whole new kind of hell. IMO, of course.

All large apps are a pain regardless of the framework. It's called coupling.

Building your application as a series of small applications that work with each other is a solution that has worked for me.
