Swoole 协程与高性能 PHP 开发

Swoole 让 PHP 支持协程，大幅提升 IO 密集型场景性能。

1. 安装

pecl install swoole

2. HTTP 服务器

use Swoole\Http\Server;



$server = new Server('0.0.0.0', 9501);

$server->on('request', function ($request, $response) {

    $response->header('Content-Type', 'application/json');

    $response->end(json_encode(['message' => 'Hello Swoole']));

});

$server->start();

3. 协程并发请求

use Swoole\Coroutine;

use Swoole\Coroutine\Http\Client;



Coroutine\run(function () {

    $urls = ['http://httpbin.org/get', 'http://httpbin.org/ip'];

    $wg = new Coroutine\WaitGroup();



    foreach ($urls as $url) {

        $wg->add();

        Coroutine::create(function () use ($url, $wg) {

            $client = new Client($url, 80);

            $client->get('/');

            echo $client->body;

            $wg->done();

        });

    }

    $wg->wait();

});

4. 连接池（Redis/MySQL）

使用 Swoole\Coroutine\Channel 实现连接池，复用连接，提升性能。

Swoole 将 PHP 带入高性能领域。
