Designing PHP Service Classes for Clean Architecture

As PHP applications grow, stuffing business logic into controllers or database models leads to brittle, hard-to-test code. Learning how to isolate this logic into dedicated service classes is the key to building scalable and clean software. In this text-based course, you will transition from writing monolithic scripts to designing elegant, decoupled PHP architectures, making your codebase significantly easier to maintain, test, and extend. What you'll learn: - Understand the fundamental role of service classes in modern PHP architecture - Apply SOLID design principles specifically to service layer implementation - Manage dependencies effectively using dependency injection and modern PHP type hinting - Implement modern PHP features like constructor property promotion and readonly classes - Separate business logic from controllers, HTTP requests, and database persistence layers - Write clean, testable service class code with strict types and clear interfaces This course begins with foundational architectural concepts and definitions before moving step-by-step through refactoring messy code into clean, modern service classes. You will analyze written code examples and learn to structure your applications like an industry professional. Designed for PHP developers who understand basic syntax, this course requires no prior experience with advanced design patterns. Start reading today to write cleaner, more professional PHP code.
