Workerman Development: How to implement remote desktop control based on TCP protocol

Introduction:
Remote desktop control is a common technology that allows users to Network remote control of a desktop interface on a computer. Remote desktop control based on TCP protocol is an efficient and stable method. This article will introduce how to use Workerman to develop remote desktop control based on TCP protocol and provide specific code examples.

1. What is Workerman?
Workerman is an open source high-performance PHP socket server framework that enables PHP developers to develop high-performance TCP/UDP/UnixSocket applications just like developing Node.js. Compared with traditional PHP servers, Workerman uses non-blocking IO and asynchronous event-driven models to support large-scale concurrent connections.

2. The principle of remote desktop control
Remote desktop control based on TCP protocol mainly includes two parts: server and client. The server is responsible for receiving the client's connection request and sending the received desktop interface information to the client. The client is responsible for connecting to the server and rendering and displaying the received desktop interface information. The specific workflow is as follows:

1. After the server is started, it listens to the specified port.
2. The client connects to the server and establishes a TCP connection.
3. The server sends the desktop interface information to the client.
4. The client renders and displays the desktop interface information after receiving it.
5. Real-time interaction between server and client.

3. Use Workerman to realize remote desktop control

1. Server-side code example:

   <?php
   require_once __DIR__ . '/vendor/autoload.php';
   
   use WorkermanWorker;
   
   $desktop_worker = new Worker('tcp://0.0.0.0:5678');
   
   $desktop_worker->onConnect = function ($connection) {
    echo "Client connected
   ";
   };
   
   $desktop_worker->onMessage = function ($connection, $data) {
    // TODO: 处理桌面界面信息
    $connection->send($desktop_info);
   };
   
   $desktop_worker->onClose = function ($connection) {
    echo "Client closed
   ";
   };
   
   Worker::runAll();

2. Client-side code Example:

   <?php
   require_once __DIR__ . '/vendor/autoload.php';
   
   use WorkermanWorker;
   
   $desktop_client = new Worker();
   
   $desktop_client->onConnect = function ($connection) {
    echo "Connected to server
   ";
   };
   
   $desktop_client->onMessage = function ($connection, $data) {
    // TODO: 渲染桌面界面
   };
   
   $desktop_client->onClose = function ($connection) {
    echo "Server closed
   ";
   };
   
   $desktop_client->connect('tcp://127.0.0.1:5678');
   
   Worker::runAll();

IV. Summary
This article introduces how to use Workerman to develop remote desktop control based on TCP protocol, and provides specific code examples. By using Workerman, we can implement remote desktop control functions efficiently and stably, providing users with a better experience.
