PHP OOP: Build Your Own Web Framework from Scratch

Many developers can write basic PHP scripts, but structuring clean, maintainable applications requires mastering Object-Oriented Programming (OOP). In this text-only course, you will transition from procedural PHP to building a custom, lightweight web framework from scratch. By reading clear explanations and working through practical code-based exercises, you will develop a deep mental model of OOP principles and modern PHP architecture. You will learn to write code that is modular, testable, and aligned with current industry standards. What you'll learn: - Understand core OOP pillars including inheritance, polymorphism, encapsulation, and abstraction. - Implement modern PHP features such as strict typing, namespaces, and constructor property promotion. - Configure Composer autoloading and implement PSR standards for clean, interoperable code. - Build a custom routing system to handle HTTP requests and map them to controllers. - Create a reusable database abstraction layer and a basic template engine. - Structure a fully functional model-view-controller (MVC) architecture from the ground up. The course begins with foundational concepts, defining classes, objects, and properties, before guiding you step-by-step through the architectural decisions needed to assemble your own framework. This course is designed for PHP beginners who understand basic syntax and variables but want to master OOP and application architecture. No advanced framework experience is required.
