There is full working PHP code to connect to a database and enter stuff in my "Some Simple PHP Classes for Managing PayPal Instant Payment Notifications[^]" article that might be useful. It doesn't address the data source side of your problem, but takes care of the rest. Of course, you will have to modify it to write to the correct tables and columns for your case.
