PHP模拟多线程请求代码示例

下面是PHP模拟多线程请求代码示例

        multi_threads_request($nodes){
        $mh = curl_multi_init();
        $curl_array = array();
        foreach($nodes as $i => $url)
        {
            $curl_array[$i] = curl_init($url);
            curl_setopt($curl_array[$i], CURLOPT_RETURNTRANSFER, true);
            curl_multi_add_handle($mh, $curl_array[$i]);
        }
        $running = NULL;
        do {
            usleep(10000);
            curl_multi_exec($mh,$running);
        } while($running > 0);

        $res = array();
        foreach($nodes as $i => $url)
        {
            $res[$url] = curl_multi_getcontent($curl_array[$i]);
        }

        foreach($nodes as $i => $url){
            curl_multi_remove_handle($mh, $curl_array[$i]);
        }
        curl_multi_close($mh);
        return $res;
    }

    print_r(multi_threads_request(array(
        'http://www.open-open.com',
        'http://www.baidu.com',
    ));
    ?>
