PHP help needed[Urgent]

I want some help on PHP coding for a payment gateway !

Information


My Payment gateway provider returns a value 0 , if the payment was successful, and other values ranging from 1 to 9 , in case of error.

Now, problem, is :-

I have passed the status value (which i get from payment gateway after payment) to $status , and have the following below code for it...

if ($status != 0) {
$error_message = "Transaction Failed. Code: " . $status; }

Code (markup):

Now it works fine and echo's this ,

" Transaction Failed. Code: THE STATUS CODE HERE"



But what i want is, it should echo the status description message and not the status code.


The status messages are given below ..

function getResponseDescription($status) {

    switch ($status) {
        case "0" : $result = "Transaction Successful"; break;
        case "?" : $result = "Transaction status is unknown"; break;
        case "1" : $result = "Unknown Error"; break;
        case "2" : $result = "Bank Declined Transaction"; break;
        case "3" : $result = "No Reply from Bank"; break;
        case "4" : $result = "Expired Card"; break;
        case "5" : $result = "Insufficient funds"; break;
        case "6" : $result = "Error Communicating with Bank"; break;
        case "7" : $result = "Payment Server System Error"; break;
        case "8" : $result = "Transaction Type Not Supported"; break;
        case "9" : $result = "Bank declined transaction (Do not contact Bank)"; break;
        case "A" : $result = "Transaction Aborted"; break;
        case "C" : $result = "Transaction Cancelled"; break;
        case "D" : $result = "Deferred transaction has been received and is awaiting processing"; break;
        case "F" : $result = "3D Secure Authentication failed"; break;
        case "I" : $result = "Card Security Code verification failed"; break;
        case "L" : $result = "Shopping Transaction Locked (Please try the transaction again later)"; break;
        case "N" : $result = "Cardholder is not enrolled in Authentication scheme"; break;
        case "P" : $result = "Transaction has been received by the Payment Adaptor and is being processed"; break;
        case "R" : $result = "Transaction was not processed - Reached limit of retry attempts allowed"; break;
        case "S" : $result = "Duplicate SessionID (OrderInfo)"; break;
        case "T" : $result = "Address Verification Failed"; break;
        case "U" : $result = "Card Security Code Failed"; break;
        case "V" : $result = "Address Verification and Card Security Code Failed"; break;
        default  : $result = "Unable to be determined"; 
    }
    return $result;
}

Code (markup):

I have made above function to get STATUS Message, but how should i echo them ?



I mean,


what shall i write in

if ($status != 0) {
$error_message = "Transaction Failed. Code: " . $status; }

Code (markup):

so $error_message = "gives output of status response description"


Thank You

 

$error_message = "Transaction Failed. Code: " . $status; }

Code (markup):

Could that not be:

$error_message = "Transaction Failed. Code: " . $result; }

Code (markup):

?

EDIT:
Oops. Didn't see the function. Do what the others say.

 

$error_message = "Transaction Failed. Code: " . getResponseDescription($status);

But I want to comment on something more important: it is not a good idea to give the zero value to success. Zero is the default for any variable, so it should not be the value for process success, you know what I mean? Let it be 100 or any other number. Now, zero means success and means no variable at all.

 

or

$error_message = "Transaction Failed. Code: " . $status . " Error: " . getResponseDescription($status);

PHP:

 

Thanks it worked

i can not change zero values, as that is being returned from MasterCard in case of success payment.
