What is PHP middleware and how do I use it?

PHP middleware is a type of software that acts as a bridge between different applications or services. It processes requests and responses in a web application, allowing you to add functionality like authentication, logging, or error handling.

Can you give me an example of how to implement middleware in a PHP application?

Sure! In a PHP application using a framework like Laravel, you can create middleware by defining a class that implements the handle method. This method receives the request and a closure to call the next middleware.

What are some common use cases for middleware?

Common use cases for middleware include user authentication, request logging, CORS handling, and input validation.

How do I test my middleware?

You can test your middleware by writing unit tests that simulate requests and check the responses or side effects of your middleware.
