The Complete Php Object Oriented Programming Course 2025

A complete beginner’s guide to mastering OOP in PHP with real-world examples and simple explanations.

What you'll learn

Understand the fundamentals of Object-Oriented Programming (OOP) in PHP, including classes, objects, properties, and methods.

Master core OOP principles such as encapsulation, inheritance, polymorphism, and abstraction.

Learn how to use visibility (public, private, protected) and constructors/destructors properly.

Apply namespaces, autoloading (PSR-4), and traits to write modular, scalable code.

Explore advanced OOP concepts like interfaces, abstract classes, dependency injection, and design patterns.

Understand how to write testable, reusable, and extensible OOP code for larger applications and frameworks like Laravel or Symfony.

Internalizing OOP Best Practices and Standards

Learning to Think in Terms of Objects and Responsibility

Understanding Class Design and Code Structure

Building a Strong Theoretical Foundation in PHP OOP

Requirements

A basic understanding of PHP syntax and programming logic, such as variables, functions, conditionals, and loops.

Experience writing simple procedural PHP scripts (e.g., contact forms, login systems, etc.).

Description

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.
