How to use PHP and Unity3D combined with Workerman to implement a real-time chat system in the game

Introduction:
With the development of network technology, the real-time chat system in the game has become essential in game development a part of. This article will show you how to implement a simple real-time chat system in the game by combining PHP, Unity3D and Workerman framework.

1. Preparation work
Before starting the implementation, we need to prepare the following tools and environment:

1. Unity3D Development Environment
2. PHP Development Environment
3. Workerman Framework

2. Implement the real-time chat system in the game in Unity3D

1. Create a UI interface to display chat content and input boxes.
2. Send a POST request through UnityWebRequest to transfer the chat information to the backend.
3. Parse the data returned from the backend and display the chat information on the UI interface.

Code example:

using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Networking;
using System.Collections;

public class ChatManager : MonoBehaviour
{
    public InputField inputField;
    public Text contentText;

    public void SendChatMessage()
    {
        string message = inputField.text;

        StartCoroutine(PostChatMessage(message));
    }

    IEnumerator PostChatMessage(string message)
    {
        WWWForm form = new WWWForm();
        form.AddField("message", message);

        using (UnityWebRequest www = UnityWebRequest.Post("http://yourdomain.com/chat.php", form))
        {
            yield return www.SendWebRequest();

            if (www.isNetworkError || www.isHttpError)
            {
                Debug.Log(www.error);
            }
            else
            {
                contentText.text = www.downloadHandler.text;
            }
        }
    }
}

3. Implement back-end processing in PHP

1. Create a chat.php file to receive chats sent by Unity3D information.
2. In the chat.php file, use the Workerman framework to monitor client connections and broadcast the received chat messages to all online players.

Code example:

<?php
require_once 'Workerman/Autoloader.php';

use WorkermanWorker;

$ws_worker = new Worker("websocket://0.0.0.0:8000");

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

$ws_worker->onMessage = function ($connection, $message) use ($ws_worker) {
    foreach ($ws_worker->connections as $client_connection) {
        $client_connection->send($message);
    }
};

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

Worker::runAll();

IV. Conclusion
Through the above implementation, we can implement a simple real-time chat system in the game. Of course, this is just a basic example, and you can expand and optimize the functions according to actual needs. I hope this article will be helpful to developers who are learning how to use PHP and Unity3D combined with Workerman to implement a real-time chat system in the game.
