Quiz

1.

Which PHP function was used to uppercase the category title strings?

2.

Why don't the store_item_size and store_item_color tables contain any primary or unique keys?

Answers

1.

strtoupper()

2.

Presumably, you will have items with more than one color and more than one size. Therefore, item_id is not a primary or unique key. Also, items may have the same colors or sizes, so the item_color and item_size fields must not be primary or unique either.
