How to use Aura.Router for URL routing in php?

As one of the common web development languages, PHP provides some convenient and practical tools to help developers quickly build web applications. One of them is Aura.Router, a simple yet effective URL routing library that allows developers to define routes to match requested URLs and preprocess the requests before they are sent to the controller. In this article, we will cover how to use Aura.Router for URL routing.

1. Introduction to Aura.Router

Aura.Router is a PHP library, open source using the MIT license, which provides a fast and simple way to handle URL routing. It is designed to easily handle complex routing situations in web applications. Aura.Router does not require any external dependencies and therefore can be easily integrated into existing projects.

2. Install Aura.Router

Before you start using Aura.Router, you need to install it in your project. You can install it by using Composer:

composer require aura/router

3. Define routing

Defining routing is one of the key steps in using Aura.Router. By defining a route, you specify the requested URL, HTTP method, and required controllers and actions. Here is a sample route definition:

use AuraRouterRouterContainer;

$routerContainer = new RouterContainer();
$map = $routerContainer->getMap();

$map->get('blog.read', '/blog/{id}', function($request, $response) {
    $id = $request->getAttribute('id');

    $response->write('You are reading post ' .$id);
    return $response;
});

In the above example, we have created a route named "blog.read" that uses the HTTP GET method to request the "/blog/{id}" URL pattern . When a route matches, the provided controller function is called, passing it the request and response objects. In this example, we get the "id" parameter from the request and render it using the response object.

4. Obtain and execute matching routes

Once routes are defined, they need to be matched when requests enter the application. To do this, you can use the Matcher class of Aura.Router as shown below:

$request = ZendDiactorosServerRequestFactory::fromGlobals();

$matcher = $routerContainer->getMatcher();
$route = $matcher->match($request);

if ($route) {
    $response = call_user_func($route->handler, $request, $response);
} else {
    // Handle 404 Not Found
}

In the above example, we get the HTTP request from the global variable and then get the Matcher instance of Aura.Router and use to find matching routes. If a matching route is found, the handler function specified in the route definition is called. Otherwise, you can customize the handling of the request (such as returning an HTTP 404 Not Found response).

5. Conclusion

Aura.Router provides a flexible and scalable routing solution for PHP applications. In this article, we showed you how to use Aura.Router to create custom routes and match routes based on the route definition when a request reaches your application. I hope this article was helpful and can help you better build PHP web applications with advanced routing capabilities.
