I'd suggest choosing one of the many MVC frameworks for PHP (http://www.phpframeworks.com/ http://www.phpframeworks.com/) and reading that framework's tutorials and guides then getting to work on a real project. For example, there's a series of tutorials for Yii (http://www.larryullman.com/series/learning-the-yii-framework/ http://www.larryullman.com/series/learning-the-yii-framework...) as well as an intro to the concepts behind the MVC pattern (http://www.larryullman.com/2009/10/08/understanding-mvc/ http://www.larryullman.com/2009/10/08/understanding-mvc/)
