Workerman and PHP collaborative development: building high-performance Web applications
Introduction:
In today's era of rapid development of the Internet, the high performance of Web applications has become important for user experience and competitiveness. factor. As a widely used server-side development language, PHP's performance optimization has always attracted much attention. This article will introduce how to use Workerman and PHP to develop collaboratively to build high-performance web applications.
- Introduction to Workerman
Workerman is a high-performance PHP Socket server framework that provides powerful network programming capabilities. Compared with traditional PHP applications, Workerman has lower resource consumption and higher concurrent processing capabilities. It supports multiple transport protocols, including TCP, UDP, Unix Domain Socket, etc., and can be easily integrated into existing PHP applications.
- Example: Implement a simple Chat application
Below we use an example to demonstrate how to use Workerman and PHP for collaborative development to build a simple Chat application. The application allows multiple users to chat online at the same time.
Step 1: Install Workerman
First, we need to install Workerman, which can be installed through Composer:
composer require workerman/workerman
Step 2: Create a WebSocket server
Next, we can create a PHP file named chat_server.php to create a WebSocket server and handle communication with the client:
<?php
use WorkermanWorker;
// 創(chuàng)建一個Worker監(jiān)聽8080端口，以WebSocket協(xié)議通訊
$ws_worker = new Worker('websocket://0.0.0.0:8080');
// 設(shè)置進(jìn)程數(shù)量
$ws_worker->count = 4;
// 當(dāng)接收到客戶端的連接成功事件時
$ws_worker->onConnect = function ($connection) {
echo "New connection
";
};
// 當(dāng)接收到客戶端的消息事件時
$ws_worker->onMessage = function ($connection, $data) use ($ws_worker) {
// 將收到的消息發(fā)送給所有客戶端
foreach ($ws_worker->connections as $client_connection) {
$client_connection->send($data);
}
};
// 運行Worker
Worker::runAll();Step 3: Create a WebSocket client
At the same time, we can also create an HTML file named index.html, which is used to create a WebSocket client and communicate with the server:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Chat</title>
<script src="https://cdn.jsdelivr.net/npm/vue"></script>
<script>
var ws = new WebSocket("ws://127.0.0.1:8080");
ws.onmessage = function(event) {
var message = event.data;
console.log("Received message: " + message);
};
function sendMessage() {
var message = document.getElementById("message").value;
ws.send(message);
}
</script>
</head>
<body>
<div id="app">
<input type="text" id="message" v-model="message">
<button @click="sendMessage">發(fā)送</button>
</div>
<script>
new Vue({
el: '#app',
data: {
message: ''
},
methods: {
sendMessage: function() {
var message = this.message;
if (message !== '') {
ws.send(message);
this.message = '';
}
}
}
})
</script>
</body>
</html>Step 4: Start the service and Test
Finally, we start the server through the command line and open the index.html file on the browser to start chatting:
php chat_server.php start
Conclusion:
Through the above example, we have achieved a simple Chat application, developed collaboratively with PHP using Workerman. Workerman provides powerful network programming capabilities, allowing us to build high-performance web applications. Be sure to focus on performance optimization and provide a good user experience.
Working principle:
Workerman is based on PHP's Socket function and uses non-blocking I/O and event-driven models. It listens to network events in a loop and handles connections and message sending and receiving in a non-blocking manner. This design enables Workerman to have excellent performance and is suitable for high-concurrency web application scenarios.
Note:
- Workerman needs to install common PHP extensions (such as pcntl, posix and event). Please ensure that these extensions have been installed and enabled.
- Before deploying to the production environment, please test and debug the code carefully to ensure the stability and security of the program.

Summary:
Through the introduction of this article, we have learned how to use Workerman and PHP to develop collaboratively to build high-performance Web applications program. This is just a simple example. In actual applications, we can expand functions and optimize performance according to needs. I hope this article can inspire PHP developers and help them build better web applications.
