Frequently Asked Questions

What does symfony/http-kernel do?

The symfony/http-kernel package offers a well-organized process for transmuting a Request into a Response. Leveraging the EventDispatcher component, this package has the flexibility to create full-stack frameworks, micro-frameworks or even advanced CMS systems like Drupal. It plays a critical role in managing HTTP requests and handling responses in an application.

How do you use symfony/http-kernel?

To use the symfony/http-kernel in your PHP projects, you will first have to install the package using Composer. You can do so with the following command:

composer require symfony/http-kernel

Then, you can make use of it in your PHP code. Here's an elementary example of how you can utilize the HttpKernel:

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpKernel\HttpKernel;
use Symfony\Component\HttpKernel\Controller\ControllerResolver;
use Symfony\Component\EventDispatcher\EventDispatcher;

$dispatcher = new EventDispatcher();
$resolver = new ControllerResolver();

$kernel = new HttpKernel($dispatcher, $resolver);

$request = Request::createFromGlobals();
$response = $kernel->handle($request);

$kernel->terminate($request, $response);

In this example, we create a new instance of the HttpKernel with an EventDispatcher and a ControllerResolver. Then, we create a Request object from the global PHP variables. This Request object is then passed to the handle method of our kernel, which will return a Response. Lastly, this response is sent to the client, and the request-response cycle is terminated.
