What is RESTful API design, and how have you implemented it in your previous projects using PHP?
RESTful API design focuses on creating APIs that adhere to REST (Representational State Transfer) principles. In PHP, I use frameworks like Laravel to build RESTful APIs. This involves defining routes, handling HTTP methods (GET, POST, PUT, DELETE), and returning appropriate HTTP status codes and responses. RESTful APIs are stateless, scalable, and can be consumed by various clients, making them suitable for modern web applications.
