Assuming you mean that the PHP script is on a web server somewhere and the desktop app is hitting it over HTTP, it's no different than any other response. Anything you print will be sent back to the client, in this case your desktop a.. So if you want to send XML back, you'd build a string with your XML (either manually or using the DOM or SimpleXML APIs or a 3rd party like QueryPath or whatever floats your boat) and print it, just as you would HTML.

Note that you may need to explicitly set headers with header() to make sure the desktop app reads it properly.

My question is simply this: What is the preferred method for passing this

without converting it to an array or XML or an object or something? How do I 
return the
data in the recordset to the desktop app?

Thanks for your advice.
