Returning a recordset to a desktop app

Hi All. I have a Windows desktop app that I created using Visual Foxpro (a database app). I want to write a PHP script that I will call from my desktop app. The script will simply query a MySQL database on my web server and return the recordset to the desktop app. My question is simply this: What is the preferred method for passing this recordset back to the desktop app? I'm assuming that there's no reasonable way to send a recordset back 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. Ken Watkins
