PHP OOP Classes & Objects

PHP Object Oriented Programming (OOP)

From PHP 5, you can also write PHP code in an object-oriented style.

What are Classes and Objects?

A class is a template for objects, and an object is an instance of a class.

  • Class: e.g., Car
  • Object: e.g., Volvo, Audi, Toyota

When the individual objects are created, they inherit all the properties and behaviors from the class, but each object will have different values for the properties.
