Swoole and Workerman's choice of data transfer modes between PHP and MySQL

Swoole and Workerman’s choice of data transfer modes between PHP and MySQL

Introduction:
In PHP applications, data interaction with the MySQL database is very Common needs. In PHP network programming, Swoole and Workerman are two commonly used open source frameworks, which provide high-performance network communication capabilities. This article will compare Swoole and Workerman's choices in PHP and MySQL data transmission modes, and give specific code examples.

1. Swoole
Swoole is a high-performance asynchronous PHP network communication engine. Its bottom layer is written in C language and can directly interact with the operating system kernel. Compared with traditional PHP network programming, Swoole has higher concurrency capabilities and lower resource consumption. The following is a sample code for using Swoole to realize data transmission between PHP and MySQL:

<?php
// 创建一个Swoole的TCP服务器
$server = new SwooleServer('127.0.0.1', 9501);

// 监听连接事件
$server->on('Connect', function ($server, $fd) {
    echo "Client {$fd} connected
";
});

// 监听数据接收事件
$server->on('Receive', function ($server, $fd, $fromId, $data) {
    // 连接MySQL数据库
    $conn = new mysqli('localhost', 'root', 'password', 'database');
    // 执行SQL查询操作
    $result = $conn->query($data);
    // 处理查询结果
    // ...
    // 返回查询结果
    $server->send($fd, $result);
    // 关闭数据库连接
    $conn->close();
});

// 监听关闭连接事件
$server->on('Close', function ($server, $fd) {
    echo "Client {$fd} closed
";
});

// 启动服务器
$server->start();

In the above code, we created a Swoole TCP server and listened to three events: connection, data reception and connection closing. When the client connects successfully, the Connect event will be triggered; when the client sends data, the Receive event will be triggered. In this event, we can connect to the MySQL database and execute SQL queries. Operation; finally, return the query results to the client and close the database connection. When the client disconnects, the Close event is triggered.

2. Workerman
Workerman is a high-performance PHP asynchronous network communication framework. It is written in pure PHP and does not need to rely on other extensions. Workerman handles network requests in an event-driven manner, featuring low latency and high concurrency. The following is a sample code for using Workerman to transfer data between PHP and MySQL:

<?php
// 引入Workerman的自动加载文件
require_once __DIR__ . '/vendor/autoload.php';

use WorkermanWorker;

// 创建一个Worker监听端口，创建MySQL数据库连接
$worker = new Worker('tcp://127.0.0.1:9502');
$worker->onWorkerStart = function ($worker) {
    // 连接MySQL数据库
    $conn = new mysqli('localhost', 'root', 'password', 'database');
    $worker->conn = $conn;
};

// 客户端连接时触发的事件
$worker->onConnect = function ($connection) use ($worker) {
    echo "Client {$connection->id} connected
";
};

// 客户端发送数据时触发的事件
$worker->onMessage = function ($connection, $data) use ($worker) {
    // 执行SQL查询操作
    $result = $worker->conn->query($data);
    // 处理查询结果
    // ...
    // 返回查询结果给客户端
    $connection->send($result);
};

// 客户端断开连接时触发的事件
$worker->onClose = function ($connection) {
    echo "Client {$connection->id} closed
";
};

// 启动Worker
Worker::runAll();

In the above sample code, we created a Workerman Worker instance and listened to port 9502. In the Worker's onWorkerStart event, a MySQL database connection is created, which can be used throughout the Worker's life cycle. When the client connects successfully, the onConnect event will be triggered; when the client sends data, the onMessage event will be triggered, in which the MySQL database is connected and the SQL query operation is performed; Finally, the query results are returned to the client. When the client disconnects, the onClose event is triggered.

Summary:
Both Swoole and Workerman provide high-performance network communication capabilities and play a very good role in data transmission between PHP and MySQL. Which framework to choose can be chosen based on project needs, development experience and personal preferences. The above is an introduction to Swoole and Workerman's choice of PHP and MySQL data transmission modes. I hope it will be helpful to readers.
