How PHP and Unity3D use Workerman to implement the server-side push function

In modern network applications, the server-side push function (Server Push) shows its powerful power. It can push information to the client in real time without the client constantly making requests to the server. In this article, we will discuss how to implement server-side push functionality using the Workerman framework using PHP and Unity3D.

Workerman is a high-performance event-driven development framework written in pure PHP. It provides us with a TCP/UDP long connection server, which can easily implement the server-side push function.

First, we need to build a basic Workerman server to handle the push function. We create a file named PushServer.php and add the following code:

require_once __DIR__ . '/vendor/autoload.php';
use WorkermanWorker;
use WorkermanLibTimer;

$pushServer = new Worker();
$pushServer->count = 1;

$pushServer->onWorkerStart = function($pushServer) {
    // 创建一个定时器，每隔一秒向客户端推送消息
    Timer::add(1, function() use ($pushServer) {
        foreach ($pushServer->connections as $connection) {
            $connection->send('推送一条消息');
        }
    });
};

Worker::runAll();

In the above code, we imported the relevant classes of Workerman and created a Worker instance named $pushServer. Then we set the number of processes for this instance to 1, and implemented the function of pushing one message to the client every second in the onWorkerStart callback function.

Next, we use Unity3D to create a client application to receive server-side push messages. We create a new scene in Unity3D and create a C# script called PushClient.cs and attach it to a game object in our scene. Add the following code:

using UnityEngine;
using WebSocketSharp;

public class PushClient : MonoBehaviour
{
    private WebSocket ws;

    void Start()
    {
        // 连接到服务器
        ws = new WebSocket("ws://127.0.0.1:2345");
        ws.Connect();

        ws.OnMessage += (sender, e) =>
        {
            // 接收到服务器推送的消息
            Debug.Log("收到推送消息：" + e.Data);
        };
    }

    private void OnDestroy()
    {
        // 断开与服务器的连接
        ws.Close();
    }
}

In the above code, we use a third-party library called WebSocketSharp to implement WebSocket connection. In the Start function, we connect to the server where PushServer.php is located and set the OnMessage event callback function to receive messages pushed by the server. In the OnDestroy function, we disconnect from the server.

Finally, we attach the PushClient.cs script to a game object in Unity3D and run the Unity3D application. Then, go to the directory where PushServer.php is located in the terminal and run the following command to start the Workerman server:

php PushServer.php start

Now, when we run the Unity3D application, we will see the reception per second in the Unity3D console to a push message from the server.

In this article, we learned how to implement server-side push functionality using the Workerman framework using PHP and Unity3D. Workerman provides us with a fast, high-performance, and easy-to-use solution. I hope that through the introduction of this article, readers will have a certain understanding of this and be able to flexibly apply it in their own projects.
