Explaining MVC Frameworks and what it means for a designer

I have a buddy that codes all the PHP for my sites I design and I do the HTML, CSS, JQuery.

He’s talking about starting to get into using frameworks such as CakePHP. I did some light reading on it, and ran into this MVC concept.

What does using a framework/MVC mean for someone like me who does graphics and markup?

Absolutely nothing unless you’re gonna help him in PHP.
