How to use the Hyperf framework for performance optimization

Introduction:
Hyperf is a high-performance PHP framework based on Swoole extension, with coroutines, annotations, and dependency injection and other characteristics. In large-scale applications, optimizing performance is crucial. This article will introduce how to use the Hyperf framework for performance optimization and provide specific code examples.

1. Using coroutines
Coroutines are one of the core features of the Hyperf framework. Asynchronous programming can be achieved through coroutines. Asynchronous calls can greatly improve the concurrency and performance of applications and avoid blocking waiting situations. In the Hyperf framework, you can use coroutines to perform operations such as database queries, HTTP requests, and cache reading and writing. The following is an example of using coroutines:

use HyperfDiAnnotationInject;
use SwooleCoroutine;

class UserService
{
    /**
     * @Inject()
     * @var HyperfDatabaseConnectionInterface
     */
    private $connection;

    public function getUser($id)
    {
        return Coroutine::create(function () use ($id) {
            $user = $this->connection->selectOne("select * from users where id = ?", [$id]);
            Coroutine::suspend(); // 挂起当前协程
            return $user;
        });
    }
}

2. Using cache
Cache is one of the important means to improve application performance. The Hyperf framework provides a cache manager that makes it easy to use various cache drivers. The following is an example of using cache:

use HyperfDiAnnotationInject;
use HyperfCacheCacheManager;

class UserService
{
    /**
     * @Inject()
     * @var CacheManager
     */
    private $cacheManager;

    public function getUser($id)
    {
        return $this->cacheManager->remember("user:$id", function () use ($id) {
            return User::find($id);
        }, 3600);
    }
}

In the above code, the cache manager is used to obtain user information through the remember method. If it exists in the cache, it is returned directly, otherwise it is obtained and stored from the database. into cache.

3. Use connection pool
Connection pool is an effective method to improve network request performance and can reduce the consumption of connection establishment and closing. In the Hyperf framework, you can use connection pools to manage database connections, Redis connections, HTTP clients, etc. The following is an example of using a connection pool:

use HyperfDiAnnotationInject;
use HyperfDbConnectionDb;

class UserService
{
    /**
     * @Inject()
     * @var Db
     */
    private $db;

    public function getUser($id)
    {
        return $this->db->connection()->selectOne("select * from users where id = ?", [$id]);
    }
}

4. Using annotations and dependency injection
The Hyperf framework supports component management and configuration through annotations and dependency injection. Using annotations can simplify code writing and maintenance and improve development efficiency. The following is an example of using annotations and dependency injection:

use HyperfDiAnnotationInject;
use HyperfRpcClientJsonRpcClient;

class OrderService
{
    /**
     * @Inject()
     * @var JsonRpcClient
     */
    private $rpcClient;

    public function createOrder($userId, $productId)
    {
        $result = $this->rpcClient->call('order.create', [$userId, $productId]);
        return $result;
    }
}

In the above example, dependency injection on JsonRpcClient is implemented through the @Inject annotation, thereby achieving remote calls to the order service.

Summary:
Good performance is the core competitiveness of an application. By rationally using the features and tools of the Hyperf framework, the performance of the application can be effectively improved. In this article, we introduce how to use features such as coroutines, caches, connection pools, annotations, and dependency injection for performance optimization, and provide specific code examples. I hope readers can improve their development capabilities and project performance through the guidance of this article.
