OOP

This project shows an order management system using object-oriented design in PHP. It features customer creation, product addition, and order state management through the State pattern and a Facade for abstraction. Structured with src for core classes and tests for PHPUnit testing, the code also utilizes PHPCS, PHPStan, and security checks to ensure quality. Ideal as a starting point or learning aid for applying OOP principles like encapsulation, inheritance, and dependency injection.
