If you store the data the way you are, the only way to find a record is
by searching through the array (there are ways to get PHP do the
searching, but it still requires searching).
An alternative data organization is to make an array of arrays that you
index with the animal and color values to get the rate. Something like:
$rates = array( // Animals
0 => array ( // Colors => Rate
0 => 5,
1 => 10,
2 => 15,
),
1 => array ( // Colors => Rate
0 => 20,
1 => 25,
2 => 30,
),
....
);
