Object Oriented Programming with PHP

What is OOP

OOP was first invented for the purpose of physical modelling in the Simula-67.

Whilst there is no hard and fast definition of what Object Oriented Programming (OOP) is, we can define. So lets just use this loose definition for now and it is left to reader to make up their own minds about what a decent definition is. Object Oriented Programming (OOP) is a programming concept that treats functions and data as objects. OK, not the best definition but gives us an opening. The key word here is objects. As we progress through this tutorial we will see how data and functions can be represented as re-usable objects, thus cutting down on code and time.
