Slightly off topic but worth mentioning is:

If your $products array is generated dynamically, make sure it isn't
empty before running the query, MySQL does NOT like:

"SELECT product_name FROM accessories WHERE product_id IN ()"

The empty "()" will cause a MySQL error (it won't just return an empty
result set.)  Plus, why run the query if the array is empty anyway?
