Workerman Development Example Sharing: Achieving High Stability Chat System

Introduction:
With the rapid development of the Internet, chat systems have become an indispensable part of people's daily lives. Implementing a stable and reliable chat system is every developer's dream. This article will develop a highly stable chat system using the Workerman framework and provide code examples. Workerman is a high-performance asynchronous socket framework for PHP with excellent concurrent processing capabilities and stability.

1. Install Workerman

Before starting to use Workerman, we need to ensure that the PHP environment has been installed. First, we need to execute the following command in the terminal to install Workerman:

composer require workerman/workerman

2. Create server and client

  1. Server

Create a File named server.php and add the following code:

<?php
require_once __DIR__ . '/vendor/autoload.php'; // 引入Workerman库

use WorkermanWorker;

$server = new Worker("websocket://0.0.0.0:8000"); // 监听8000端口

$server->onConnect = function ($connection) {
    echo "New Connection
";
};

$server->onMessage = function ($connection, $message) {
    foreach ($connection->worker->connections as $clientConnection) {
        $clientConnection->send($message); // 将消息发送给所有客户端
    }
};

Worker::runAll();

The above code creates a WebSocket server that listens to the local port 8000. When a new connection is established, "New Connection" will be output. When a message is sent to the server, the server sends the message to all connected clients.

  1. Client

Create a file named client.html and add the following code:

<!DOCTYPE html>
<html>
<head>
    <script>
        var socket = new WebSocket("ws://localhost:8000");

        socket.onopen = function () {
            console.log("Connected");
        };

        socket.onmessage = function (event) {
            console.log("Message received: " + event.data);
        };

        socket.onclose = function () {
            console.log("Connection closed");
        };

        function sendMessage() {
            var message = document.getElementById("message").value;
            socket.send(message);
        }
    </script>
</head>
<body>
    <input type="text" id="message">
    <button onclick="sendMessage()">Send</button>
</body>
</html>

The above code creates a WebSocket client , establish a connection with our server.

3. Run the chat system

  1. Run the server

Execute the following command in the terminal to run the server:

php server.php start

If all goes well, you should be able to see "New Connection" output.

  1. Open the client

Open the client.html file in the browser, enter the message in the input box, and click the "Send" button to send the message. You should be able to see "Message received" output in the server terminal.

Conclusion:
Through this example, we successfully implemented a highly stable chat system using the Workerman framework. Workerman's high performance and asynchronous processing capabilities allow us to handle large numbers of concurrent connections, resulting in a high-quality chat experience. I hope this article will help you understand and use Workerman.
