Implementing Observer, Strategy, and Adapter Design Patterns in PHP for Modular Solutions
This article explains three design patterns: Observer, Strategy, and Adapter, using PHP. The Observer pattern allows subjects to notify observers of state changes, facilitating event-driven programming. The Strategy pattern enables flexible behavior changes by switching between different algorithms or methods at runtime. The Adapter pattern bridges incompatible interfaces, allowing objects to work together seamlessly. Examples for each pattern include email notifications and logging (Observer), logging strategies for databases and files (Strategy), and integrating MySQL and PostgreSQL clients (Adapter). The article emphasizes modularity, dependency injection, and proper class design to improve code maintainability and scalability.
