If you need a data base to use with PHP, also use MySQL. PHP and MySQL are not either/or, they work together. If you are simply trying to add options to a base selection, you don't need a database. You simply register the variables for the session from page to page.

Using logic (if/else) in PHP, it should be fairly easy to populate fields through a number of choices. If for some reason you need to use the data on a return visit, then you do need a database. However, if you are simply transferring data to a shopping cart or a form, you do not.
