How to use Workerman to implement the real-time message push function of PHP and Unity3D

Overview:
In modern web development, real-time message push has become an increasingly important functional requirement. Whether it is online chat, real-time notifications, game data synchronization, etc., real-time message push can provide a better user experience. PHP and Unity3D are two widely used technology stacks. How to implement real-time message push through them. This article will introduce the use of Workerman framework to achieve this function.

Workerman Introduction:
Workerman is a high-performance asynchronous event-driven network library developed based on PHP, which provides powerful network programming functions. Compared with traditional PHP applications, using Workerman can easily implement high-concurrency, low-latency network applications. Moreover, Workerman is also very suitable for implementing real-time data push functions.

Use Workerman to implement real-time message push in PHP:
First, we need to install Workerman. Open the terminal and execute the following command:

composer require workerman/workerman

Next, we create a file named push.php and write the following code:

<?php
require_once __DIR__ . '/vendor/autoload.php';
use WorkermanWorker;
use WorkermanConnectionTcpConnection;

$worker = new Worker("tcp://0.0.0.0:2345");

$worker->onMessage = function(TcpConnection $connection, $data) {
    // 向所有连接的客户端推送消息
    foreach($connection->worker->connections as $client) {
        $client->send($data);
    }
};

Worker::runAll();

The above code creates a TCP service that listens on on port 2345. When a client connects and sends a message, the message is pushed to all connected clients.

Use Workerman to implement real-time message push in Unity3D:
Unity3D is a very popular game development engine. We can use C# in Unity3D to implement real-time message subscription.

First, we open Unity3D, create a new script file, and name it MessageSubscriber.cs. Write the following code in the script:

using UnityEngine;
using WebSocketSharp;

public class MessageSubscriber : MonoBehaviour
{
    private WebSocket websocket;

    void Start()
    {
        websocket = new WebSocket("ws://localhost:2345");

        websocket.OnMessage += (sender, e) =>
        {
            string message = e.Data;
            Debug.Log(message);
        };

        websocket.Connect();
    }

    void OnDestroy()
    {
        if (websocket != null && websocket.ReadyState == WebSocketState.Open)
        {
            websocket.Close();
        }
    }
}

The above code uses the WebSocketSharp library to create a WebSocket instance and connect to the server. When a message arrives, the message processing logic is triggered through the OnMessage event.

Complete real-time message push example:
Below we will integrate PHP and Unity3D code examples to demonstrate how to implement a complete real-time message push function.

1. Create a new scene in Unity3D and add a cube object.
2. Mount the MessageSubscriber.cs script file on the cube.
3. Add some logic to the PHP code, such as connecting to the database, user authentication, etc.
4. In the code for pushing messages, filter the target users according to actual needs and push messages only to specific users.
5. In the message processing logic of Unity3D, the game scene is operated accordingly based on the content of the received message.

Through the above steps, we can receive and process messages sent by PHP in Unity3D in real time, thereby achieving the function of real-time message push.

Summary:
Using the Workerman framework, you can easily implement the real-time message push function between PHP and Unity3D. Through the code of the above example, we can easily implement the real-time messaging function in our own projects and improve the user experience. Of course, in actual use, we can further optimize and expand according to needs. I hope this article will help you understand Workerman and implement real-time message push.
