Paypal回复总金额显示错误

Question

我已将PayPal发票整合到我的网站中。虽然我已经创建了一个项目，共有3877个，但Paypal响应json显示了wronly。

我们已粘贴了此代码的一些部分，用于创建发票。

PHP代码

function doCreateAndSendInvoice($aryData, $aryItems)
        {
            $this->end_url = $this->getEndPoint("createAndSendInvoice");
            $strCreateAndSendInvoice = $this->prepareCreateInvoice($aryData, $aryItems);
            $response = $this->curlRequest($strCreateAndSendInvoice);
            $aryRresponse = explode("&", $response);
            $response = $this->parseCurlResponse($aryRresponse);
            return $response;
        }
                $aryData['language'] = "en_US";
                $aryData['merchantEmail'] = 'xxx@mail.com';//$business;
                $aryData['payerEmail'] = $get_user->email;
                $aryData['currencyCode'] = "USD";
                $aryData['orderId'] = 123;//strtotime('now');
                $aryData['invoiceDate'] = date('Y-m-d\TH:i:s\Z',strtotime($this->input->post('invoice_date')));
                $aryData['dueDate'] =date('Y-m-d\TH:i:s\Z',strtotime($this->input->post('due_date')));
                $aryData['paymentTerms'] = "Net45"; 
                $aryData['merchantFirstName'] = "Pheonix ";
                $aryData['merchantLastName'] = "Solutions";
                $aryData['merchantBusinessName'] = "Pheonix Solutions";
                 $aryData['merchantWebsite'] = "https://www.website.com";
                $aryData['merchantCustomValue'] = "xxxxx";
                $aryData['merchantLine1'] = "xxxx";
                $aryData['merchantLine2'] = "xxxx";
                $aryData['merchantCity'] = "xxx";
                $aryData['merchantState'] = "xxxx";
                $aryData['merchantPostalCode'] = "xxx";
                $aryData['merchantCountryCode'] = "xx";

                $aryData['billingFirstName'] = "Billing First Name";
                 $aryData['billingLine1'] = 'xxxx';
                // $aryData['billingLine2'] = "Billing Line 2";
                $aryData['billingCity'] = 'xxxx';
                $aryData['billingState'] = 'xxxx';
                $aryData['billingPostalCode'] = 'xxxx';

                $aryData['billingCountryCode'] = 'xxxx';
                # code...
                $aryItems[0]['name'] = 'title';
                $aryItems[0]['quantity'] = 1;
                $aryItems[0]['unitprice'] = 3877;

                 $res = $this->doCreateAndSendInvoice($aryData, $aryItems);
                    print_r($res);

输出： 上面代码的输出。
