How to implement TCP/UDP communication in Workerman documentation

How to implement TCP/UDP communication in the Workerman document requires specific code examples

Workerman is a high-performance PHP asynchronous event-driven framework that is widely used to implement TCP and UDP communication. This article will introduce how to use Workerman to implement TCP and UDP-based communication and provide corresponding code examples.

1. TCP communication

1. Create TCP server

It is very simple to create a TCP server using Workerman, just write the following code:

<?php
require_once __DIR__ . '/vendor/autoload.php';

use WorkermanWorker;

// 创建一个Worker监听9090端口的TCP连接
$tcp_worker = new Worker('tcp://0.0.0.0:9090');

// 设置开启多少个进程
$tcp_worker->count = 4;

// 当收到客户端发送的数据时触发
$tcp_worker->onMessage = function($connection, $data) {
    // 处理数据
    // ...
    // 向客户端发送数据
    $connection->send("Hello, I have received your message: $data
");
};

// 运行worker
Worker::runAll();

2. Create TCP client

<?php
require_once __DIR__ . '/vendor/autoload.php';

use WorkermanWorker;

// 创建一个TCP连接到服务器
$tcp_client = new Worker('tcp://127.0.0.1:9090');

// 当连接建立成功时触发
$tcp_client->onConnect = function($connection) {
    // 向服务器发送数据
    $connection->send('Hello Server');
};

// 当服务器返回数据时触发
$tcp_client->onMessage = function($connection, $data) {
    echo "Receive data from server: $data
";
};

// 运行worker
Worker::runAll();

2. UDP communication

1. Create UDP server

Workerman provides a special The Worker class is used to create a UDP server. The following is a code example to create a UDP server:

<?php
require_once __DIR__ . '/vendor/autoload.php';

use WorkermanWorker;

// 创建一个Worker监听9999端口的UDP连接
$udp_worker = new Worker('udp://0.0.0.0:9999');

// 当收到客户端发送的数据时触发
$udp_worker->onMessage = function($connection, $data) {
    // 处理数据
    // ...
    // 向客户端发送数据
    $connection->send("Hello, I have received your message: $data
");
};

// 运行worker
Worker::runAll();

2. Create a UDP client

Different from the TCP client, the UDP client No need to connect to the server, just send data. The following is a code example for creating a UDP client:

<?php
require_once __DIR__ . '/vendor/autoload.php';

use WorkermanWorker;

// 创建一个UDP连接到服务器
$udp_client = new Worker('udp://127.0.0.1:9999');

// 当接收到服务器返回的数据时触发
$udp_client->onMessage = function($connection, $data) {
    echo "Receive data from server: $data
";
};

// 向服务器发送数据
$udp_client->send('Hello Server');

// 运行worker
Worker::runAll();

Summary:

This article introduces how to use the Workerman framework to implement TCP and UDP communication, and provides corresponding code examples. Workerman makes it easy to create TCP and UDP servers for simple and efficient data interaction. I hope readers can master the basic usage of the Workerman framework through this article and further improve their technical capabilities in network communications.
