dissecting Custom MIGS payment response with ob_get_contents()

xrgt · February 26, 2007

How can i strip the following output and access the variables via an array?

The buffered output i'm expecting is always in the following format:

<html><body>
processingError=
<br>
processingErrorMessage=
<br>
transactionApproved=
<br>
responseCode=
<br>
transactionNo=
<br>
receiptNo=
<br>
merchantTXRef=
<br>
transactionDeclined=
<br>
creditCardExpired=
<br>
insufficientFunds=
</body></html>

This is the payment module code i'm trying to work with:

<?php
// Get result
$vpcResponse = ob_get_contents();
// Finish with the buffer
ob_end_clean(); 
// Check for errors
if(strchr($vpcResponse,"<html>")) $errorMessage = $vpcResponse;
else if(curl_error($clientURL)) $errorMessage = "CURL ERROR: " . curl_errno($clientURL) . " " . curl_error($clientURL);
// Close the connection
curl_close($clientURL);
$responseKeyVals = split("&", $vpcResponse);
 foreach ($responseKeyVals as $val) {
	  $param = split("=", $val);
	  $responseArray[urldecode($param[0])] = urldecode($param[1]);
 }
// Process the results and determine the transactions status
$transactionResponse = $responseArray['responseCode'];
?>

Thanks.

In Java i'd do it this way - PHP i have no idea, can anyone assist?:

resp = new BufferedReader(new InputStreamReader(gateway.openStream()));

	resp.readLine();
String inputLine2=resp.readLine();
	resp.readLine();
String inputLine4=resp.readLine();
	resp.readLine();
			String inputLine6=resp.readLine();
	resp.readLine();
			String inputLine8=resp.readLine();
//and so on...

paymentDetail.setResponseCode(inputLine8.substring(13,inputLine8.length()));
paymentDetail.setTransactionNo(inputLine10.substring(14,inputLine10.length()));
paymentDetail.setReceiptNo(inputLine12.substring(10,inputLine12.length()));

For anyone that is interested, this is what i came up with by modifying the existing code:

<?php
$content2 = str_replace(array("<html>", "<body>", "<br>"), "", $vpcResponse);

			$responseKeyVals = split("\r\n", $content2);
			foreach ($responseKeyVals as $val) {
				$param = split("=", $val);
				$responseArray[urldecode($param[0])] = urldecode($param[1]);
			}
?>
<?php echo $responseArray['responseCode']; ?>
