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;

// 创建一个Worker监听端口，使用异步IO
$worker = new Worker('tcp://0.0.0.0:8282');
$worker->count = 4; // 设置Worker进程数量

// 处理客户端连接
$worker->onConnect = function ($connection) {
    // 处理连接逻辑
};

// 处理客户端消息
$worker->onMessage = function ($connection, $data) {
    // 处理消息逻辑
};

// 运行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;

// 创建一个连接池实例
$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);

// 创建一个Worker处理业务逻辑
$worker = new Worker('tcp://0.0.0.0:8282');
$worker->count = 4; // 设置Worker进程数量

$worker->onMessage = function ($connection, $data) use ($pool) {
    $mysql = $pool->borrow(); // 从连接池中获取一个连接
    $result = $mysql->query('SELECT * FROM users');
    // 处理查询结果逻辑
    $pool->return($mysql); // 将连接归还到连接池
};

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;

// 创建一个Worker
$worker = new Worker('tcp://0.0.0.0:8282');
$worker->count = 4; // 设置Worker进程数量

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

// 处理客户端消息
$worker->onMessage = function ($connection, $data) use ($redis) {
    $result = $redis->get($data); // 从Redis缓存中读取数据
    // 处理查询结果逻辑
};

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;

// 创建一个Worker
$worker = new Worker();
$worker->count = 1; // 设置Worker进程数量

// 添加一个定时任务，每隔1分钟执行一次
$worker->addTimer(60, function () {
    // 执行定时任务逻辑
});

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.
