rob_illinois,
What version of PHP are you running? And what Database Background is it?
You would have to script it for each form as the script needs to know what data fields to record and where to put them.
For exporting to excel, I started with PEAR, it has an example on how to write excel files (which you can generate so long as you can get the info into PHP).
Truely, the easiest way would be to export to CSV, there is lots of tutorials on that, which you could open in excel, format, etc for export.
There is information on pulling it from an SQL Database Here.
You can get a step by step lesson on forms here
Good Luck
