在整合swoole http server和phalcon，server.php如下：

<?php

use Phalcon\DI;
use Phalcon\Loader;
use Phalcon\Mvc\Router;

        $loader->registerDirs(array(
            '../apps/controllers/',
            '../apps/models/'
        ));

        $loader->register();
    }

    /**
     * This methods registers the services to be used by the application
     */
    protected function registerServices()
    {

        $di = new DI();

        //Registering a router
        $di->set('router', function(){

        });

        //Registering a dispatcher
        $di->set('dispatcher', function(){

        });

        //Registering a Http\Response
        $di->set('response', function(){

        //Registering the Models-Metadata
        $di->set('modelsMetadata', function(){

        });

        $di->set('modelsManager', function(){
            return new ModelsManager();
        });

        $this->setDI($di);
    }

    public function main()
    {
        $this->registerServices();
        $this->registerAutoloaders();
    }
}

$application = null;

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

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

        if (!empty($request->get)) {

            $_REQUEST += $_GET;
        }

        if (!empty($request->post)) {
            $_POST = $request->post;
            $_REQUEST += $_POST;
        }

        if (!empty($request->cookie)) {
            $_COOKIE = $request->cookie;
        }

        global $application;
        $html = $application->handle($request->server['request_uri'])->getContent();
        $response->end($html);
    } catch (\Exception $e){
        print_r($e);
        echo $e->getMessage();
    }
});

$http->on('WorkerStart', function($server, $workerId) {
    global $application;
    $application = new Application();
    $application->main();
});
# 启动服务器
$http->start();

浏览器访问没什么问题
做ab测试就报错了

ab -n 10000 -c 1000 -rk http://phalcon.com/
