# Middleware

The `Middleware.php` file in your application is designed to manage and execute a stack of middleware components. Middleware components are used to process HTTP requests before they reach the controller and after the controller has generated a response. This allows for a clean separation of concerns, enabling you to handle tasks such as authentication, logging, and request modification in a modular and reusable way.

## `add()`

```php
<?php
public function add(callable $middleware) {
    $this->middlewares[] = $middleware;
}
```

* Adds a middleware to the stack.
* The middleware should be a callable (function or method) that takes the route and a next function as parameters.

## `handle()`

```php
<?php
public function handle($route, callable $next) {
    $this->index = 0;
    $this->next($route, $next);
}
```

* Starts the middleware handling process.
* Resets the index and calls the `next` method to begin executing the middleware stack.

Conclusion

The `Middleware.php` file provides a robust framework for managing middleware in your application. By allowing middleware components to be added dynamically and executed in sequence, it ensures that your application can handle complex request processing scenarios in a clean and maintainable way. Whether you need to perform authentication, logging, or any other pre-processing tasks, the middleware stack makes it easy to modularize and reuse your code.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.cmsfullform.com/documents/core/middleware.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
