If you were using the correct column type in MySQL, DECIMAL, you
shouldn't have to worry about the decimal places. Otherwise, you can use
number_format() on $order_total.
Also, the while() loop isn't needed, since only one row is returned from
a query like that without a GROUP BY clause. Also, you don't need the
quotes around $order_total when printing it out.
