The Adapter Pattern in PHP: From Code Chaos to Clean Architecture

The Adapter Pattern transforms messy PHP code into clean, flexible architecture by allowing incompatible interfaces to work together. It creates a bridge between client code and existing classes through a common interface. Using payment processing and file storage examples, the article demonstrates how to replace complex if/switch statements with clean adapter implementations. This approach reduces coupling, improves maintainability and testability, and follows SOLID principles, resulting in organized architecture that's easy to extend and modify.
