Hi tamouse,
with my untrained eye - it appears that this is what is 'sending out'
$data = sendXMLviaCurl($xmlRequest,$gatewayURL);
and this might be what is 'responding back' on the same page
$gwResponse = @new SimpleXMLElement((string)$data);
you can see these lines towards the bottom at - // Process Step Three...

the page code is long - so i cut out some extra lines - but this is
