PHP OOP Introduction

From PHP5, you can also write PHP code in an object-oriented style.

Object-Oriented Programming is faster and easier to execute.

What is OOP?

OOP stands for Object-Oriented Programming.

Object-Oriented Programming (OOP) is a programming paradigm that focuses on creating reusable code structures called objects.

In PHP, OOP allows you to define classes, which are blueprint templates for creating objects that encapsulate data and behavior.

Object-oriented programming has several advantages over procedural programming:

  • OOP is faster and easier to execute
  • OOP provides a clear structure for the programs
  • OOP helps to keep the PHP code DRY “Don’t Repeat Yourself”, and makes the code easier to maintain, modify and debug
  • OOP makes it possible to create fully reusable applications with less code and shorter development time

PHP – What are Classes and Objects?

Classes and objects are the two main aspects of object-oriented programming.

Look at the following illustration to see the difference between class and objects:

Classes:

  • Cars
  • Fruits

Objects:

Suppose we have objects from cars, like Toyota, Volvo, and Suzuki.

From fruits class, we can say banana, apple, and mango are the object.
