Разработка платежного шлюза — Обработка и обработка параметров / ключей PHP для Json, Json для Stack Overflow

Я написал файл Payment processor.php для получения параметров из системы электронной торговли, а затем отправки в PSP (поставщик платежных услуг), затем этот ответ Json от PSP будет декодирован, проверен, а ключи преобразованы и проанализированы в системе электронной торговли таким образом. :

header("Location: ".$hosturl."orderprocessor?
orderid=$custref&sig=".$_POST['SessionId']);

Прежде чем выдать товар в корзину пользователям.

$ hosturl был определен как
$ Hosturl = «локальный: 8080 / ЕКП /»;
в другом файле

Результат, который я получаю каждый раз, когда я оформляю корзину с файлом «Payment processor.php», это просто белый экран. Я должен видеть интерфейс PSP, чтобы получать данные карты пользователя вместо этого.

URL PSP является; » https://developers.paystack.co/reference#paystack-standard-x«Я следую примеру PHP cURL для справки.

Пожалуйста, помогите, если в моем коде обнаружены исправления.

Это мой файл Payment processor.php:
