异步协程开发指南：构建高可用的PHP微服务架构

<?php

use SwooleHttpRequest;
use SwooleHttpResponse;
use SwooleHttpServer;

$http = new Server("0.0.0.0", 9501);

$http->on('request', function (Request $request, Response $response) {
    $userId = $request->get['id'];

    // 异步查询用户信息
    go(function () use ($response, $userId) {
        $userData = getUserInfo($userId);

        $response->header('Content-Type', 'application/json');
        $response->end(json_encode($userData));
    });
});

function getUserInfo($userId)
{
    // 模拟数据库查询
    // ...

    return [
        'id' => $userId,
        'name' => 'John',
        'email' => 'john@example.com',
  ];
}

$http->start();
