How to use PHP and Unity3D combined with Workerman to achieve real-time data synchronization

When developing multiplayer online games or real-time data interaction applications, real-time data synchronization is a very important function. By using PHP and Unity3D combined with Workerman, we can easily achieve real-time data synchronization and transmission.

1. Installing and configuring Workerman

First, we need to install and configure Workerman on the server. Workerman is a high-performance PHP socket framework that can be used to build real-time applications. For specific installation and configuration steps, please refer to Workerman’s official documentation.

2. PHP side code implementation

On the PHP side, we need to write code to receive and process the real-time data sent by Unity3D. The following is a simple PHP code example:

<?php
use WorkermanWorker;

// 创建一个Worker监听指定的端口
$worker = new Worker('websocket://0.0.0.0:2345');

// 当有客户端连接时，触发onConnect事件
$worker->onConnect = function($connection) {
    echo "New connection
";
};

// 当收到客户端发送的数据时，触发onMessage事件
$worker->onMessage = function($connection, $data) {
    echo "Received data: $data
";
    // 在这里处理接收到的数据
    // 可以将数据存储到数据库或者转发给其他客户端
};

// 当有客户端断开连接时，触发onClose事件
$worker->onClose = function($connection) {
    echo "Connection closed
";
};

// 运行Worker
Worker::runAll();

In the above code, we created a WebSocket listener. When a client connects, sends data, or disconnects, the corresponding events are triggered respectively. You can process the received data in the onMessage event, such as storing it in a database or forwarding it to other clients.

3. Unity3D side code implementation

On the Unity3D side, we need to use the WebSocket protocol for data transmission with the PHP server. First, we need to import the WebSocket library, for example by downloading the WebSocket-Sharp library.

Then, create a C# script in Unity3D, the following is a simple example:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using WebSocketSharp;

public class DataSync : MonoBehaviour
{
    WebSocket ws;

    // 连接到服务器
    void Start()
    {
        // 创建WebSocket实例，并指定服务器地址和端口
        ws = new WebSocket("ws://localhost:2345");

        // 注册事件，当连接成功时触发
        ws.OnOpen += (sender, e) =>
        {
            Debug.Log("Connected to server.");
        };

        // 注册事件，收到服务器发送的数据时触发
        ws.OnMessage += (sender, e) =>
        {
            Debug.Log("Received data: " + e.Data);
        };

        // 注册事件，当连接关闭时触发
        ws.OnClose += (sender, e) =>
        {
            Debug.Log("Disconnected from server.");
        };

        // 连接到服务器
        ws.Connect();
    }

    // 发送数据到服务器
    void Update()
    {
        // 检测用户输入，发送数据到服务器
        if (Input.GetKeyDown(KeyCode.Space))
        {
            ws.Send("Hello server!");
        }
    }

    // 关闭连接
    void OnApplicationQuit()
    {
        ws.Close();
    }
}

In the above code, we create a WebSocket instance and connect to the server at the beginning. We also registered 3 events: OnOpen, which is triggered when the connection is successful; OnMessage, which is triggered when data sent by the server is received; OnClose, which is triggered when the connection is closed. You can send data to the server in the Update method, such as sending a message when the user presses the space bar.

Through the above code implementation of PHP and Unity3D, we successfully realized the synchronization and transmission of real-time data. You can expand and optimize the code according to actual needs. At the same time, we can also use more features of Workerman, such as scheduled tasks, multi-process mode, etc., to meet more application scenarios.

Summary

Using PHP and Unity3D combined with Workerman, we can easily achieve real-time data synchronization and transmission, thereby developing multi-player online games or real-time data interaction applications. The PHP side code is responsible for receiving and processing the data sent by Unity3D, while the Unity3D side code is responsible for data transmission with the PHP server through the WebSocket protocol.
