異步 HTTP 客戶端：async-http-php

async-http-php 是個異步 HTTP 客戶端，機遇 crul_mulit*，系統很簡單，速度非常快。

如果你想使用 ssl 或者其他來請求一個網站，你可以實現一個 task 類和 TaskInterface 接口：

date_default_timezone_set("PRC");
require dirname(dirname(__FILE__)) . DIRECTORY_SEPARATOR . 'vendor' . DIRECTORY_SEPARATOR . 'autoload.php';

$async = new \Jenner\Http\Async();
$task = \Jenner\Http\Task::createGet("http://www.baidu.com");
$async->attach($task, "baidu");

$task2 = \Jenner\Http\Task::createGet("http://www.sina.com");
$async->attach($task2, "sina");

$task3 = \Jenner\Http\Task::createGet("http://www.qq.com");
$async->attach($task3, "qq");

/**
 * you can do something here before receive the http responses
 * eg. query data from mysql or redis.
 */

while(true){
    // nonblock
    if(!$async->isDone()){
        echo "I am running" . PHP_EOL;
        sleep(1);
        continue;
    }

    $result = $async->execute();
    print_r($result);
    break;
}

/**
 * or you just call execute. it will block the process until all tasks are done.
 * $result = $async->execute();
 * print_r($result);
 */
