How to use ReactPHP with CakePHP?

CakePHP is a popular PHP framework that helps developers build web applications quickly. Supporting the use of ReactPHP in CakePHP can greatly improve the performance and efficiency of your application. This article will introduce how to use ReactPHP with CakePHP.

1. Install ReactPHP

To use ReactPHP in CakePHP, you need to install ReactPHP first. You can use Composer to install, the command is as follows:

composer require react/http:^0.8.5

After the installation is completed, you should see the ReactPHP folder in the vendor directory.

2. Create ReactPHP service

Using ReactPHP in CakePHP requires creating a ReactPHP service. Create the Server.php file in the app/src/Http/Server/ directory and add the following code:

namespace AppHttpServer;

use ReactHttpServer as HttpServer;
use ReactSocketServer as SocketServer;

class Server
{
    private $server;

    public function __construct($port)
    {
        $this->server = new HttpServer(function ($request, $response) {});

        $socket = new SocketServer('0.0.0.0:' . $port);
        $this->server->listen($socket);
    }

    public function run()
    {
        $this->server->run();
    }
}

This code creates a simple ReactPHP service, listens to the specified port, and responds to each request Returns a blank response.

3. Integrate ReactPHP service

In order to use ReactPHP service in CakePHP, it needs to be integrated in the application. Create the Controller.php file in the app/Http directory and add the following code:

namespace AppHttp;

use AppHttpServerServer;
use CakeControllerController as BaseController;

class Controller extends BaseController
{
    public function initialize()
    {
        parent::initialize();
        $this->loadComponent('RequestHandler');

        $server = new Server(8080);
        $server->run();
    }
}

This code creates a ReactPHP service in the controller and runs the service when the controller is initialized.

4. Testing

Now you can use the browser or command line to test the ReactPHP service. Visit http://localhost:8080 in your browser and you should see a blank response. You can use the curl command on the command line to test:

curl http://localhost:8080

5. Add ReactPHP controller

In order to better use the ReactPHP service, you need to create a ReactPHP controller. Create the ReactPHPController.php file in the app/Http/Controller directory and add the following code:

namespace AppHttpController;

use AppHttpServerServer;
use CakeControllerController;

class ReactPHPController extends Controller
{
    public function initialize()
    {
        parent::initialize();
        $this->loadComponent('RequestHandler');
    }

    public function index()
    {
        $server = new Server(8080);
        $server->run();
    }
}

This code creates a ReactPHP controller and creates a ReactPHP service in the index method of the controller.

6. Configure routing

In order to access the ReactPHP controller, routing needs to be configured. Add the following code to the config/routes.php file:

use CakeRoutingRouteBuilder;

$routeBuilder->connect('/reactphp', ['controller' => 'ReactPHP', 'action' => 'index']);

This code maps the URL /reactphp to the index method of the ReactPHP controller.

7. Testing

You can now test the ReactPHP service using a browser or command line. Visit http://localhost:8080/reactphp in your browser and you should see a blank response.
