Please do not top post. It makes the sequence very hard to read.
I agree with Denis and J.O. - they have a much better way of handling
this. But some other comments:
1. Why use 0, 1 and 2? Why not "bear", "tiger" and dog" for the animal,
and "black", "brown" and "white" for the color (as an example)? This
will be much easier to understand. And the HTML, if correctly defined,
can return these as easily as 0,1 and 2.
Additionally - if this is all you will ever have, then what you have may
work fine. The main question I would have is - if you have to change
the rate, add a color, or whatever - how much code are you going to have
to change?
If you ever are going to have something different, my suggestion would
be to start using a database such as MySQL or PostgreSQL now. Using a
database means that all you have to do is update the database for new
items or attributes or a rate change, and the results will be reflected
in all of your pages. The database will also handle the searches for you.
It takes a bit more work up front, but will save in the long run. It
will also be easier to start using a database now then to try to change
your code later.
