Zan: High-Concurrency HTTP Service Framework Based on PHP Coroutines

Introduction

Zan is a network service framework based on PHP coroutines that provides a simple way to develop high-concurrency HTTP servers for C10K+ level traffic. This means that Zan can easily handle tens of thousands of concurrent connections, offering powerful tools for developers to build high-performance network service applications.

Features of the Zan Framework

Coroutine Implementation

Zan framework uses PHP's coroutine technology to achieve high-concurrency network services. In traditional multi-process or multi-thread models, each connection consumes server resources. However, with the coroutine model, a single thread can handle multiple connections simultaneously, significantly reducing connection overhead. As a result, Zan's performance is much improved compared to traditional frameworks.

High Concurrency Capacity

Facing C10K+ level concurrent connections, Zan framework can easily cope. Its coroutine model allows a single thread to handle a large number of concurrent requests without additional thread overhead. This enables Zan to perform excellently in high-concurrency scenarios.

Easy to Use

Zan framework is designed to be simple, offering easy-to-use API interfaces. Developers can quickly get started with Zan to develop high-performance network service applications. For example, the following code demonstrates how to create a simple HTTP server:

use Zan\Framework\Network\Http\Server;
$server = new Server("0.0.0.0", 8080);
$server->start();

Using Zan Framework

Installation and Configuration

To get started with Zan framework, you first need to install it. You can install the latest version of Zan using composer with the following command:

composer require zanphp/zan-framework

Once installed, you can configure various parameters of Zan framework through the configuration file, such as the IP and port to listen on. The configuration file is typically named `config.php` and can be modified as needed.

Writing Application Code

In Zan framework, you can use Zan's context to handle HTTP requests, such as retrieving request parameters and processing business logic. Here is a simple example:

use Zan\Framework\Foundation\Core\RunMode;
$http = Zan\Framework\Network\Http\Server::createServer($config);
$http->onRequest(function($request, $response) {
    $response->end('Hello, Zan!');
});
$http->listen();

In the code above, we create an HTTP server and listen for incoming requests. When a request arrives, the server calls the `onRequest` callback function, where we can write the logic for handling the request. In this simple example, we just return a string.

Conclusion

Zan is a network service framework based on PHP coroutines that offers easy-to-use, high-concurrency features through PHP coroutine technology and optimized design. Developers can use Zan to build high-performance network service applications and easily handle C10K+ level concurrent connections.
