Introduction to Object-oriented programming with PHP

I found a great slideshow consisting of 122 slides in which Marcus Börger made an introduction to Object-oriented programming with PHP. The presentation was made at a PHP Conference in Quebec in 2007 and the author pointed out the next topics:

1. What is OOP?
2. PHP and OOP
3. Exceptions
4. Iterators
5. Reflection
6. Patterns

 I think this will help you understand better the Object Oriented programming in PHP even if the presentation was made in 2007.
