CURL函数的GET和ＰＯＳＴ方式的两种写法（实现ajax跨域调用）

POST请求

function curl_post($url='',$postdata='',$options=array()){
        $ch=curl_init($url);
        curl_setopt($ch,CURLOPT_RETURNTRANSFER,);
        curl_setopt($ch,CURLOPT_POST,);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
        curl_setopt($ch, CURLOPT_TIMEOUT, );
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
        if(!empty($options)){
            curl_setopt_array($ch, $options);
        }
        $data=curl_exec($ch);
        curl_close($ch);
        return $data;
    }

GET请求

function curl_get($url='',$options=array()){
        $ch=curl_init($url);
        curl_setopt($ch,CURLOPT_RETURNTRANSFER,);
        curl_setopt($ch,CURLOPT_TIMEOUT,);
        if(!empty($options)){
            curl_setopt_array($ch,$options);
        }
        $data=curl_exec($ch);
        curl_close($ch);
        return $data;
    }
ex:

　　　　

$sess_id=$_POST['sess_id'];
$arr=curl_get("http://www.zb12351.com/mapi/index.php?r_type=1&ctl=uc_account&act=index&sess_id=".$sess_id);
echo $arr;
