Swoole and Workerman's delay optimization method for data connection and data transmission between PHP and MySQL

Swoole and Workerman's delay optimization method for data connection and data transmission between PHP and MySQL

Introduction:
In web development, many applications require database While operating, PHP to MySQL data connection and data transfer may be affected by delays. This article will introduce in detail how to use Swoole and Workerman to perform delay optimization on data connection and data transmission between PHP and MySQL, and provide specific code examples.

1. Swoole's delay optimization method:

1. Use connection pool:
   Swoole provides a coroutine-based MySQL connection pool, by pre-creating a certain number of connections and replicating them It can reduce the overhead of connecting and disconnecting, and avoid frequent connecting and closing the database. The following is a sample code using Swoole connection pool:

// 创建MySQL连接池
$pool = new SwooleCoroutineConnectionPool(function () {
    $db = new SwooleCoroutineMySQL();
    $db->connect([
        'host' => 'localhost',
        'port' => 3306,
        'user' => 'root',
        'password' => '123456',
        'database' => 'test',
    ]);

    return $db;
}, 10);

// 从连接池中获取一个连接
$db = $pool->get();

// 执行查询语句
$result = $db->query('SELECT * FROM users');

// 释放连接
$pool->put($db);

2. Using coroutines:
   Swoole's coroutine feature allows PHP code to perform asynchronous operations in a synchronous manner, further reducing Delay. The following is a sample code using Swoole coroutine for MySQL query:

// 开启协程
SwooleRuntime::enableCoroutine();

go(function () {
    // 创建MySQL连接
    $db = new SwooleCoroutineMySQL();
    $db->connect([
        'host' => 'localhost',
        'port' => 3306,
        'user' => 'root',
        'password' => '123456',
        'database' => 'test',
    ]);

    // 执行查询语句
    $result = $db->query('SELECT * FROM users');

    // 输出查询结果
    print_r($result);

    // 关闭连接
    $db->close();
});

2. Workerman’s delay optimization method:

1. Asynchronous database query:
   Workerman It is event-driven and can use asynchronous methods to perform database queries, thereby reducing latency. The following is a sample code that uses Workerman to asynchronously query the database:

// 引入Workerman库
require_once __DIR__ . '/Workerman/Autoloader.php';

// 创建一个Worker线程
$worker = new Worker('websocket://0.0.0.0:8000');

// 设置异步MySQL连接
$worker->onWorkerStart = function () {
    $GLOBALS['db'] = new WorkermanMySQLAsync('mysql://root:123456@localhost:3306/test');
};

// 处理客户端消息
$worker->onMessage = function ($connection, $data) {
    // 异步查询数据库
    $GLOBALS['db']->query('SELECT * FROM users', function ($result) use ($connection) {
        $connection->send(json_encode($result));
    });
};

// 运行Worker线程
Worker::runAll();

2. Using connection pool:
   Workerman's MySQL connection component provides a connection pool function by pre-creating a certain number of Connecting and reusing can reduce the overhead of connecting and disconnecting. The following is a sample code using the Workerman connection pool:

// 引入Workerman库
require_once __DIR__ . '/Workerman/Autoloader.php';

// 创建一个Worker线程
$worker = new Worker('websocket://0.0.0.0:8000');

// 设置MySQL连接池
$worker->onWorkerStart = function () {
    $GLOBALS['db'] = new WorkermanMySQLConnectionPool('mysql://root:123456@localhost:3306/test', 10);
};

// 处理客户端消息
$worker->onMessage = function ($connection, $data) {
    // 从连接池中获取一个连接
    $GLOBALS['db']->get(function ($db) use ($connection) {
        // 执行查询语句
        $db->query('SELECT * FROM users', function ($result) use ($connection, $db) {
            // 输出查询结果
            $connection->send(json_encode($result));

            // 释放连接到连接池
            $db->put();
        });
    });
};

// 运行Worker线程
Worker::runAll();

Conclusion:
By using the optimization methods provided by Swoole and Workerman, the delay in data connection and data transmission between PHP and MySQL can be effectively reduced . Choosing the appropriate optimization method can improve the performance and response speed of web applications.
