Workerman Development Tips Revealed: Practical Methods to Improve Network Application Performance

Introduction:
In the modern Internet world, the demand for high-performance network applications is getting higher and higher. As a high-performance network application framework in the PHP field, Workerman has excellent performance and flexible scalability. This article will reveal some practical methods to improve the performance of Workerman network applications and help developers make better use of this framework.

1. Using asynchronous IO
The bottom layer of Workerman uses technologies such as epoll and libevent to implement non-blocking IO operations. Developers can use asynchronous IO to improve the concurrent processing capabilities of network applications. The following is a sample code using asynchronous IO:

use WorkermanWorker;

// 創(chuàng)建一個Worker監(jiān)聽端口，使用異步IO
$worker = new Worker('tcp://0.0.0.0:8282');
$worker->count = 4; // 設(shè)置Worker進程數(shù)量

// 處理客戶端連接
$worker->onConnect = function ($connection) {
    // 處理連接邏輯
};

// 處理客戶端消息
$worker->onMessage = function ($connection, $data) {
    // 處理消息邏輯
};

// 運行Worker
Worker::runAll();

2. Use connection pool
Connections are important resources in Workerman network applications, and connection pools can help us better manage and reuse connections. The following is a sample code using a connection pool:

use WorkermanWorker;

// 創(chuàng)建一個連接池實例
$pool = new SwooleConnectionPool(function () {
    $mysql = new SwooleCoroutineMySQL();
    $mysql->connect([
        'host' => '127.0.0.1',
        'port' => 3306,
        'user' => 'root',
        'password' => '123456',
        'database' => 'test',
    ]);
    return $mysql;
}, 10);

// 創(chuàng)建一個Worker處理業(yè)務(wù)邏輯
$worker = new Worker('tcp://0.0.0.0:8282');
$worker->count = 4; // 設(shè)置Worker進程數(shù)量

$worker->onMessage = function ($connection, $data) use ($pool) {
    $mysql = $pool->borrow(); // 從連接池中獲取一個連接
    $result = $mysql->query('SELECT * FROM users');
    // 處理查詢結(jié)果邏輯
    $pool->return($mysql); // 將連接歸還到連接池
};

Worker::runAll();

3. Using cache
Cache is an important means to improve the performance of network applications. Caching technologies such as Redis or Memcache can be used in Workerman. The following is a sample code for using Redis cache:

use WorkermanWorker;
use WorkermanRedisRedis;

// 創(chuàng)建一個Worker
$worker = new Worker('tcp://0.0.0.0:8282');
$worker->count = 4; // 設(shè)置Worker進程數(shù)量

// 連接Redis
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);

// 處理客戶端消息
$worker->onMessage = function ($connection, $data) use ($redis) {
    $result = $redis->get($data); // 從Redis緩存中讀取數(shù)據(jù)
    // 處理查詢結(jié)果邏輯
};

Worker::runAll();

4. Using scheduled tasks
Scheduled tasks can be used to process some periodic operations, such as statistical data, updating cache, etc. Workerman provides the function of scheduled tasks, which can easily schedule scheduled tasks. The following is a sample code using scheduled tasks:

use WorkermanWorker;

// 創(chuàng)建一個Worker
$worker = new Worker();
$worker->count = 1; // 設(shè)置Worker進程數(shù)量

// 添加一個定時任務(wù)，每隔1分鐘執(zhí)行一次
$worker->addTimer(60, function () {
    // 執(zhí)行定時任務(wù)邏輯
});

Worker::runAll();

Summary:
Workerman is a powerful high-performance network application framework. By using asynchronous IO, connection pools, caching and scheduled tasks, you can Improve the performance and stability of web applications. We hope that the practical methods in this article can help developers make better use of Workerman and develop more efficient and stable network applications.
