php實現傳送手機驗證碼功能如下：

    //傳送手機驗證碼
    public function sendPhoneCodeMessage(){        
        vendor('SendPhoneCode.SendCode','','.php');
        $phone = I("post.phone"); 
        $randomNumber=rand(10000,99999);
        session('phoneCode',md5($randomNumber));
        cookie('phoneCode',md5($randomNumber),3600);
        $content = "您的一畝地驗證碼：".$randomNumber."。";
        $sendCode = new \SendCode();
        $codeResult = $sendCode->sendPhoneCode($phone,$content);
        if ($codeResult['message'] == "成功") {
            echo 1;
        }else{
            echo 0;
        }
    }
