如何利用PHP和Unity3D结合Workerman实现游戏中的实时聊天系统

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;
            }
        }
    }
}

<?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();
