The Complete PHP Object Oriented Programming Course 2026

Are you ready to take your PHP skills to the next level? If you've been writing basic PHP scripts using procedural code and want to learn how to write more organized, reusable, and professional-grade applications, this course is for you.

This course is a complete introduction to Object-Oriented Programming (OOP) in PHP, carefully designed for beginners and self-taught developers who may have little or no experience with OOP. You'll be guided step-by-step through the essential concepts that form the foundation of object-oriented programming, helping you truly understand not just how to write object-oriented code — but why it matters.

We’ll begin with the fundamentals of classes and objects, and you’ll quickly move on to learning about properties, methods, constructors, and visibility (public, private, protected). From there, we’ll explore powerful features like inheritance, method overriding, polymorphism, and encapsulation, showing how they can simplify complex applications and reduce code duplication.

You’ll also learn how to use abstract classes, interfaces, and traits to write flexible, extendable code that’s easier to maintain. Along the way, you'll gain clarity on how OOP promotes better code organization by separating responsibilities across well-defined objects.

The course will also cover namespaces, autoloading using PSR-4, and how to structure your application folders in a modern way. These skills are essential if you plan to work on larger projects or eventually dive into PHP frameworks like Laravel or Symfony.

Every topic is explained in simple, beginner-friendly language, with plenty of practical examples to reinforce your understanding. You won’t just memorize syntax — you’ll learn how to think in objects, break down a problem into logical components, and write clean, well-structured code that scales as your application grows.

By the end of this course, you will have a strong foundation in object-oriented PHP and the confidence to start applying these skills to your own projects — or take the next step toward learning a PHP framework with ease.
