How do I create and use middleware in PHP?

Middleware in PHP

Middleware is an important concept in PHP applications, particularly in frameworks like Laravel and Slim. It functions as a layer between the user request and the application response, allowing developers to filter and manipulate HTTP requests and responses efficiently.

Creating Middleware in PHP

To create middleware in PHP, you typically define a class that contains a method to handle the request before it is processed by your application. Below is an example of how to create and use middleware in a PHP application.


        <?php
        class ExampleMiddleware {
            public function handle($request, Closure $next) {
                // Perform actions before the request is handled
                if (!$this->isValid($request)) {
                    return response('Unauthorized.', 401);
                }

                // Call the next middleware or the application
                return $next($request);
            }

            private function isValid($request) {
                // Validation logic here
                return true; // Return true or false based on the validation
            }
        }
        ?>

Once you have defined your middleware, you can use it in your application by registering it within your routing logic or middleware stack.
