This is my database sample
id/cart_id/title/quantity
1 1 bbok1 2
2 2 book2 3
3 3 book1 2
So in this case I have book1 with a total of 4 sales and book2 with 3 sales. However if I use order by quantity it would show book2 then book1.
How do I use the query or php code to get the same item and make it book1 4 sales, book2 3 sales?

SELECT
title,
SUM(quantity) AS total_sales
FROM
books
GROUP BY
title
ORDER BY
total_sales DESC
