Can someone recommend some good resources for learning about MVC in PHP? It doesn't have to be specific to MVC in PHP. In fact, I'm looking for recommendations of materials that focus on the higher level concepts with examples that could port well to any language so even ASP.net books will be tolerated ;-)

Any recommendations for books, websites, blogs, etc would be excellent.

UPDATE: I have reviewed the MVC Learning Resources post but all of the references there seemed to be ASP.net specific. I was hoping to gather suggestions that were broader than a single language.
