In a continuing series of videos, Stefan Mischook has posted the last video discussing theory for object-oriented programming with PHP today.

I’ve released a new video that basically covers the content covered in the PDF: Classes and Objects. It is the last bit object oriented PHP theory before we jump in and start writing actual PHP code.

The video only runs about five minutes and covers the items from the PDF - a lot of the basics you'll need to know before getting into programming with objects and classes in PHP.
