Данные не сохраняются в базе данных - Laravel

Question

Я новичок в Laravel. Я занимаюсь интеграцией платежей. Заказ успешно получен с данными карты. Я хочу сохранить эти детали в БД. Я использую $ dom для загрузки ответа xml вместо simplexml_load_string.

Вот код, который я написал, чтобы получить значения ответа xml.

      public function checkStatusAndUpdateProfileId($transactionId, $response)
              {
                  $details = $this->listPayments($transactionId);
                  $secret = $details->txn_secret;
                  $token = $details->payment_token;
                  $url = env('SMART_PAYS_STATUS_URL');
                  $amount = $details->transaction_amount;

                  $fields = array(
                      'transactionSecret' => $secret,
                      'token' => $token,
                  );
                  $fields_string = '';
                  foreach ($fields as $key => $value) {
                      $fields_string .= $key . '=' . $value . '&';
                  }

                  rtrim($fields_string, '&');
                  $ch = curl_init($url);
                  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
                  curl_setopt($ch, CURLOPT_POST, 2);
                  curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);
                  $data['raw_xml'] = $xml = curl_exec($ch);
                  curl_close($ch);
                  //error_log($xml);

                  $dom = new \DOMDocument();
                  $dom->formatOutput = TRUE;
                  $dom->preserveWhiteSpace = FALSE;
                  $dom->loadXml($response);

        //           dd($response);

                      $err = $dom->getElementsByTagName('return');//errors

                  if (!empty($err))
    //                  dd($err);

                      $result = $dom->getElementsByTagName('hostResponseMessage');
                      $return_code = $dom->getElementsByTagName('hostResponseCode');
                      $code_for_db = $return_code[0]->nodeValue == "00" ? 'success' : "error";

                      $amount = $dom->getElementsByTagName('purchaseAmount');
                      $TxID1 = $dom->getElementsByTagName('transactionReference');
                      $card_holder = $dom->getElementsByTagName('cardholderName');
                      $exp_date = $dom->getElementsByTagName('expiry');
                      $card_type = $dom->getElementsByTagName('cardType');
                      $last_four = $dom->getElementsByTagName('maskedPAN');

                      $return_code = Payment::where('id', $transactionId)->update([
                          'return_code' => $code_for_db,
                          'return_message' => $result[0]->nodeValue,
                          'transaction_amount' => !empty($amount) ? $amount : 0.00,
                          'brand' => $card_type[0]->nodeValue,
                          'last4' => $last_four[0]->nodeValue,
                          'holder' => $card_holder[0]->nodeValue,
                          'expiry' => $exp_date[0]->nodeValue,
                      ]);
                      //$this->updateTransactionProfile($transactionId, $code_for_db, $result, $amount, $card_type, $last_four, $card_holder, $exp_date);
                      return $return_code;
                  }

Вот ответ xml, который генерируется из $ dom-> load Xml ($ response);

Я хочу добавить вышеуказанные значения xml в БД. Когда я передаю значения как $ amount = $ dom-> getElementsByTagName ('purchaseAmount'); он возвращает пустую строку следующим образом.

Пожалуйста, помогите мне решить эту проблему , Большая помощь Спасибо!
