MYSQL Table to Text Document

Ok i am having a reviews system on my website. Now i am also looking to give the option for people to download the review if they want to. Now i was wondering how I could take the information from the mysql database and when the button is clicked generate a text file for the person to download

use PHP and fwrite() :)

Or simply send the data trough an artificial header, but that'll require a bit more code :)

Thanks, didn't know that function was in php aswell
