I found the code from phpfreaks.com to export data from a MYSQL DB to an excel file, and it seems to work good.
What I'm trying to do is to update an existing file with this DB data. I've spent many hours googling around trying to find the solution, but always comes up with the same answer - there isn't one?
I'm almost certain it's possible to do so, but I can't seem to find the answer.
Any help possible would be highly appreciated. I'm kinda desperate!!!
