自己封装的php Curl并发处理，欢迎提出问题优化。

因为项目需要，发现一个一个发送请求实在太慢，无奈之下，我们可以封装一个并发处理的curl请求批处理句柄来减少重复创建句柄的问题

代码如下：

/*

 *@param array $data url的参数

 *@param  string $url  url地址

 *@return array $retsult  结果序列

*/

function getmulti($data,$url){

//组合url参数

$ch = array();

$mh = curl_multi_init();

$result = array();

foreach ($data as $k => $v) {

    $query[$k] = http_build_query($v);

    $ch[$k] = curl_init();

    $options = array(

        CURLOPT_URL=> $url.'?'.$query[$k],

        CURLOPT_TIMEOUT => 50,

        CURLOPT_HEADER => 0,

        CURLOPT_RETURNTRANSFER => TRUE,

);

curl_setopt_array($ch[$k], $options);

curl_multi_add_handle($mh,$ch[$k]);

}

$active = null;

// 执行批处理句柄

do {

   $mrc = curl_multi_exec($mh, $active);

} while ($active > 0);

foreach ($ch as $ck => $cv) {

    $result[] = curl_multi_getcontent($cv);

    usleep(1);

    curl_multi_remove_handle($mh, $cv);

}

curl_multi_close($mh);

//echo $options[CURLOPT_URL];die();

return $result;

}

//example：

$data = array(

                'happy'=>array('emotion'=>'happy', 'tag'=>'男人'),

                'anger'=>array('emotion'=>'anger', 'tag'=>'男人'),

                'sad'=>array('emotion'=>'sad', 'tag'=>'男人'),

                'fear'=>array('emotion'=>'fear', 'tag'=>'男人'),

                'surprise'=>array('emotion'=>'surprise', 'tag'=>'男人'),

                'none'=>array('emotion'=>'none', 'tag'=>'男人'),

        );

        $newdata = array();

        $hotres = '';

        $url = 'http://www.xxx.com/demo/getEmotionDetails.jsp';

        $startime = time().'<br />';

        echo '开始时间:'.$startime;

        foreach ($data as $k=>$v){

            //$hotres = $this->get($data, $url);

            //$hotres = $this->get($v, $url);

            $hotres = file_get_contents($url.'?'.http_build_query($v));

            //$newdata[] = object_to_array(json_decode($hotres));

            $newdata[] = $hotres;

        }

        /*      foreach ($hotres as $hk=>$hv){

         $newdata[$data[$hk]['emotion']] = object_to_array(json_decode($hv));

        } */

        echo '消耗时间:'.(time()-$startime).'<br />';

        echo '结束时间:'.time().'<br />';

        echo '<pre>';print_r($newdata);exit;
