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

We can chain properties and methods to provide fluent code and improve its readability. When a class’s methods return the `$this` keyword, they can be chained together to create more streaming code.

# How to chain methods and properties?

For example, in our `Car` class, let’s say that we want to measure how much fuel we have in our car’s tank. The amount of fuel in the tank depends on the number of miles we’ve driven in our car and the amount of fuel that we put in the tank.

In order to achieve our goal, we’ll add a public property `$tank` to our class. This represents the number of gallons of fuel that we have in the car’s tank.



We can chain properties and methods to provide fluent code and improve its readability. When a class’s methods return the `＄this` keyword, they can be chained together to create more streaming code.
