将World Pay Payment Gateway与PHP集成

Question

Implementing worldpay payment gateway is driving me nuts. I am trying to implement worldpay payment gateway in a php website using XML direct method. I am using the code from here to handle all the HTTP requests.

But whenever I try to connect to their server I get error message that Authorization is required. I have supplied all the required details in the following url

$dest="https://$merchantCode:$[e-mail]/jsp/merchant/xml/paymentService.jsp";

Even when I use curl to connect to their server I get error message that url is not found.

Following is the curl code I am using.

    $ch = curl_init ($url);
    curl_setopt($ch, CURLOPT_POST,1);
    curl_setopt($ch, CURLOPT_POSTFIELDS,$xml);   //$xml is the xml string
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_NOPROGRESS, 0);

    $result = curl_exec ($ch); // result will contain XML reply from WorldPay curl_close ($ch);
    if ( $result == false )
    {
    $error = "Curl could not retrieve page '$url', curl_exec returns false";               
    }
    echo $error;
    echo $result;

As there is no proper documentation, I request whoever has implemented it to please help me.

Currently I am testing the PHP website on my localhost. Is that the reason that the HTTP request or the curl is not working
