Hi, My name is Yazeed and i am here to tell you about Object Oriented Programming in PHP. And i thank you for choosing to learn PHP Object Oriented Programming from my tutorial.

I wrote this tutorial as i was making the transition from PHP to Java Server Pages or JSP, a transition you don't need to make.

PHP is a very compitant Object oriented Language, i am only making the switch because i have to (for some reason irrelevant to you).

Bear in mind that this tutorial does not assume you know anything about Object Oriented Programming, but it does assume you know the basics of PHP.

So, As i started reading Java, i realised that in order to make the right decisions, i should have means of comparing both languages, This tutorial is all about Object Oriented in PHP, No Java in here.

I have been using PHP for about 5 years now, and to say the least, PHP 5 and above is a good Object Oriented Language, with very few exceptions that you can work around, it is close to a full featured Object Oriented Language.

Since this tutorial is meant to be no nonsense, and streight to the point let's get started.

1- What is Object Oriented, and why should i use it ?
2- Why Object oriented, Why Not.
3- PHP 5 , Object Oriented Building Blocks
4- Constructors, Extending the vehicle example 1
5- Inheritance, Extending the vehicle example 2
6- Public, Private and protected, Access control, Who can use what

Since this is a work in progress, the following are parts i wanted to write, but still, they do not snap in just yet in the Table Of Contents above
