I was reading about this model of software development and it is very interesting. I will try to migrate my normal code to this model. Somebody is used it now? Is it really good and easier to develop with it?

MVC is useful if you would like to keep your presentation and business logic separate.

Using one of the PHP frameworks like Zend/CakePHP etc then you can benefit from code re-use, building robust applications etc.

But remember there is a learning curve involved in implementing an MVC structure. But I think its very useful once you do learn that design pattern.
