Getting Started with Yii2 Websocket

Before you get started with Yii2 Websocket, you should have a basic understanding of PHP and web development. You should also have a local development environment set up, such as XAMPP or WAMP.

Step 1: Install Yii2 Framework

The first step to getting started with Yii2 Websocket is to install the Yii2 framework. You can do this by following the instructions on the Yii2 website.

Step 2: Install Ratchet

The next step is to install Ratchet, which is a PHP library for working with WebSockets. You can install Ratchet using Composer, which is a dependency manager for PHP.

Step 3: Create a WebSocket Server

Once you have installed Ratchet, you can create a WebSocket server using the following code:

use Ratchet\Server\IoServer;use Ratchet\Http\HttpServer;use Ratchet\WebSocket\WsServer;use MyApp\MyWebSocket;require dirname(__DIR__) . '/vendor/autoload.php';
$server = IoServer::factory(new HttpServer(new WsServer(new MyWebSocket())),8080);
$server->run();

Step 4: Create a WebSocket Client

You can create a WebSocket client using JavaScript. Here is an example:

var conn = new WebSocket('ws://localhost:8080');conn.onopen = function(e) {console.log("Connection established!");};
conn.onmessage = function(e) {console.log("Message received: " + e.data);};
conn.onclose = function(e) {console.log("Connection closed!");};
