How to use Workerman to realize the multi-person collaborative editing function of PHP and Unity3D

Introduction:
In today's Internet era, multi-person collaborative editing has become a very important and common functional requirement. Whether it is document editing in team collaboration or scene editing in multiplayer online games, it is necessary to enable multiple people to edit the same file or scene at the same time. This article will introduce how to use the Workerman framework to implement the multi-person collaborative editing function of PHP and Unity3D, and provide code examples.

1. What is Workerman framework?
Workerman is a high-performance PHP socket server framework that can support tens of thousands or even hundreds of thousands of concurrent connections. It is suitable for implementing various network applications such as WebSocket, TCP, and UDP, including multiplayer online games, real-time chat, online document editing, etc.

2. Implementation Principle of Multi-person Collaborative Editing Function
Before realizing the multi-person collaborative editing function, we need to have a certain understanding of its implementation principle. Simply put, whenever an editing action occurs, the Unity3D client will send the action to the server through the WebSocket protocol. After the server receives the action, it will broadcast it to other clients, thereby achieving the effect of multi-person collaborative editing.

3. Server-side implementation
The following is a code example for implementing the server-side using the Workerman framework:

// 引入Workerman的Autoloader
require_once 'vendor/autoload.php';

use WorkermanWorker;
use WorkermanWebServer;

$web = new WebServer('http://0.0.0.0:8080');
$web->count = 1;

$ws_worker = new Worker('websocket://0.0.0.0:8000');
$ws_worker->count = 4;

$ws_worker->onWorkerStart = function ($worker) {
    echo "Worker starting...
";
};

$ws_worker->onConnect = function ($connection) {
    echo "New connection established.
";
};

$ws_worker->onMessage = function ($connection, $data) use ($ws_worker) {
    // 处理接收到的编辑动作
    // 广播给其他连接
    foreach ($ws_worker->connections as $clientConnection) {
        $clientConnection->send($data);
    }
};

$ws_worker->onClose = function ($connection) {
    echo "Connection closed.
";
};

Worker::runAll();

The above code creates a Web server and a WebSocket server. The Web server listens on port 8080 for receiving HTTP requests from Unity3D, and the WebSocket server listens on port 8000 for receiving WebSocket connections and messages from Unity3D.

4. Unity3D client implementation
The following is a code example of using Unity3D to implement the client (only the core code is shown):

using UnityEngine;
using WebSocketSharp;

public class SyncEditor : MonoBehaviour
{
    private WebSocket ws;

    void Start()
    {
        // 连接WebSocket服务器
        ws = new WebSocket("ws://localhost:8000");
        ws.Connect();
        ws.OnMessage += OnMessage;
    }

    void OnMessage(object sender, MessageEventArgs e)
    {
        // 处理接收到的编辑动作
    }

    void OnDestroy()
    {
        // 断开WebSocket连接
        ws.Close();
    }
}

The above code creates a WebSocket in the Start() method Connect and process the received editing action in the OnMessage() method.

5. Summary
By using the Workerman framework, we can easily implement the multi-person collaborative editing function of PHP and Unity3D. After the server receives the editing action sent by the Unity3D client, it will broadcast it to other clients, thereby achieving the effect of multi-person collaborative editing. The above is a simple implementation example, and readers can adjust and expand it according to actual needs.
