I need to take the following query and pull the total order counts and sum of the orders grouped by day. I'm storing everything using timestamps.

SELECT
    COUNT(id) as order_count,
    SUM(price + shipping_price) as order_sum,
    DAY(FROM_UNIXTIME(created)) as day
FROM `order`
WHERE '.implode(' AND ', $where).'

I need to group by DAY but when I do for this past weekend's sales it takes my order_count and makes it 1 instead of 3. How can I pull the above values grouped by day?

NOTE: The implode is used ONLY to define the time period (WHERE created >= TIMESTAMP AND <= TIMESTAMP)
