Object-oriented programming is perhaps the dominant development paradigm for leading languages including Java, C#, and Python. The rich class and inheritance framework wasn’t fully implemented in modern PHP until 2015, and best practices for object-oriented programming are still emerging.

This course is an introduction to object-oriented programming in PHP. You’ll start with the basics of the OOP paradigm and get familiar with classes, objects, methods, and properties. You’ll then chain methods and properties using the this keyword before working with access modifiers and magic methods. With these basics down, you’ll take a deep dive into object-oriented programming in PHP, including inheritance, abstraction, polymorphism, and namespaces. After exploring exception handling, you’ll use these object-oriented techniques to build, manage, and edit a PHP database.

By the end of this course, you’ll be prepared to build dynamic server-side applications using object-oriented programming in PHP.

Object-Oriented Programming in PHP

Previously, we learned how to organize our code using the MVC design pattern. In the following example, we will check if a car is expensive using the MVC design pattern. The data is fed to the `Model`, processed in the `Controller`, and then passed to the `View`.


## Retrieving the data from the data source

The `Model` class gets and sets the car data (in a real-world application, it will retrieve the data from the database).

# Retrieving the data from the data source

The `Model` class gets and sets the car data (in a real-world application, it will retrieve the data from the database).

Learn about retrieving data from different sources in the MVC design pattern.
