Display text files in order

Hi everyone,

I have a web site that displays prices of hotels on it. These prices are stored in separate text files so that they can be edited and displayed (using the php "include" statement) on the web page that they are supposed to be displayed on. Right now each hotel has it's own individual page where they can advertise. However, I would like to make an additional page that lists the top 10 cheapest hotels of the day. Since the prices (contained in the text files) will change all the time, this list will change all the time. I know that I can display all the prices on one page, but how do I make it so that the prices are displayed in order from lowest to highest. Is there some type of javascript code or php code that I could use to do this? Please help. I am a relative beginner and would welcome any code or help that you can provide.

Thanks

Forget javascript for this, PHP is the way to go here.
@mod: move to PHP please

If you have all the prices in an array then you can use the array sorting functions. For example natcasesort.... there's lots more.

Moved!
