短信接口自己胡改八改的倒是生效了（改成了面向过程的，没有类，只有函数）

普通的注册啥的都没问题，但是发现在订单通知时出现redeclare（或类似重复声明）错误。

查看订单通知\diy\module\order\models\Order_model.php的notice函数才知道，是通知买家、卖家双方，代码如下：

            // 通知买家
            if ($buy) {
                $this->member_model->sendsms($order['shipping_phone'], $content);
            }
            // 通知商家
            if ($sell) {
                $m = dr_member_info($sell);
                if ($m['phone']) {
                    $this->member_model->sendsms($m['phone'], $content);
                }
            }

因为面向过程，这样一来，我在的sendsms() 这个函数里的子函数就在一个被重复声明两次，请问高手，这个怎么破？

附\diy\module\member\models\Member_model.php的sendsms函数代码如下：

/**
     * 短信发送
     *
     * @param    string    $mobile
     * @param    string    $content
     * @return  bool
     */
    public function sendsms($mobile, $content) {

        $sortedQueryStringTmp = "";
        foreach ($apiParams as $key => $value) {
            $sortedQueryStringTmp .= "&" . encode($key) . "=" . encode($value);
        }

        $stringToSign = "GET&%2F&" . encode(substr($sortedQueryStringTmp, 1));

        $sign = base64_encode(hash_hmac("sha1", $stringToSign, $accessKeySecret . "&",true));

        $signature = encode($sign);
