What Database Do I Need?

I don't know what kind of database to use

[successfirst]

Hi, I need a php script written but I'm not sure what type of database I need and how many databases the script will require. I was wondering if anyone knows.

I need a script that does the following:

1. Has a few form fields (Full Name, Address, City... etc) and a few drop boxes.

2. When the form is submitted it writes the data into a xls file.

3. Every time the script is run a unique id (number) should be generated and written into the xls file together with the rest of the data.

4. Verifies that the telephone number matches the state when the form is submitted, otherwise it will return a error message.

5. Every time the form is submitted, it overwrites the existing xls file and combines the data in one file.

6. It saves the ip, date, time, and URL.

Regards,
Brandon

you can do this with mySQL, with one database and one table, perhaps two tables for the state confirmation.

Thanks a lot.
