Money Values in MySQL

[Jeremy White]

I am trying to insert values into a column that will be dollar values. They are each the price of a product in its corresponding row. The goal of this database is for it to be sortable by price. I have been able to do this, but I cannot store commas in the database with the numbers without losing the order-by-price ability. How do I store commas with integers while still being able to sort by this column?

Example:
I want to be able to input the following: 400; 1,920; 32; 147,010 and be able to order everything.

BTW, I am using PHP to interface with the database.

Thanks,
Jeremy
