Curriculum

Introduction

This introductory section begins with a general overview of the course and its objectives, setting the stage for your journey into the world of PHP OOP. The introductory lecture provides a brief overview of the course structure, expectations, and the skills you will acquire.

Setup and Environment

This section covers the essential setup required to start your learning journey. You will learn how to install XAMPP, a local web server, and configure Visual Studio Code, a powerful and user-friendly code editor, ensuring a smooth development environment for the course. The lectures detail the installation process step-by-step to ensure you have everything set up correctly before diving into the core OOP concepts.

PHP OOP Fundamentals: Classes, Objects, and More

This section lays the foundation of Object-Oriented Programming (OOP) in PHP. Starting with a clear explanation of what OOP is and why it's essential, you will delve into the core concepts of classes and objects, learn about properties and methods, understand the '$this' keyword, and grasp the significance of private properties. The section culminates with an introduction to magic methods, focusing on constructors and destructors to manage the lifecycle of objects.

Core OOP Principles: Encapsulation, Inheritance, Polymorphism, and Abstraction

This section explores the fundamental pillars of OOP. You'll learn about encapsulation to protect data integrity, inheritance to create reusable code and build class hierarchies, and polymorphism to achieve flexibility and code reusability. You will also master abstraction, a crucial concept for managing complexity. This section covers inheritance with constructors and overriding methods, and explores polymorphism through abstract classes, interfaces, and multiple interfaces, supplemented by lessons on static properties, methods and class constants.

Advanced PHP OOP: Magic Methods, Traits, and More

Building upon the foundational concepts, this section dives into advanced techniques. You'll master various magic methods including 'get', 'set', 'call', 'callStatic', 'toString', and 'invoke' enhancing code efficiency and flexibility. The section continues with an in-depth exploration of type hinting and return types, followed by an introduction to traits – a powerful mechanism for code reusability and enhancing class functionalities. Understanding trait method conflict resolution is also covered.

Mastering Namespaces and Autoloading

This section covers essential skills for managing larger projects. You'll learn how to use namespaces to organize your code effectively, avoiding naming conflicts and improving code clarity. Further, you will explore different autoloading techniques, including using the 'spl' function and Composer, a widely-used dependency manager in PHP. This will empower you to structure your application folders in a modern and professional manner.
