Разработка платежного шлюза - Обработка и обработка параметров / ключей PHP в Json, Json в PHP

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

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

Перед выдачей товара в корзину пользователям.

$ hosturl был определен как $ hosturl = "localhost: 8080 / ekp /";в другом файле

Результат, который я получаю каждый раз при оформлении заказа в корзине с файлом «Payment processor.php», это просто белый экран.Вместо этого я должен видеть интерфейс PSP, чтобы получать данные карты пользователя.

URL-адрес PSP;"https://developers.paystack.co/reference#paystack-standard-x" Я использую пример cURL PHP для справки.

любезно помогите, если в моем коде обнаружены исправления.

Это мой файл Payment processor.php: 

<?php require_once 'includes/config.inc.php' ?>
<?php
$parameters = array();

Paystack */

                 "&currency=".urlencode($_POST['currency']).
                 "&orderid=".urlencode($_POST['orderid']), $KEY);

$parameters['UserName']=$username;
$parameters['Password']=$password;
$parameters['reference']=$_POST['orderid'];
$parameters['Amount']=($_POST['amount'] * 100);
//should change SessionId' to be named reference
$parameters['SessionId']=$sig;
