CSV export from MySQL database using PHP

I have been given a script by a friend which needs amending by someone who understands PHP and MySQL to make it do what I need it to do for me on my setup. I can email the script if requested. What it needs to do is create online auction listing for a number of auction sites by extracting up to 2500 items from the database and incorporating them into a seperate HTML template for each item and the producing an output file in CSV format (excel) for upload to the auction website. Typically the auction template will include items such as product name which will be used for the title, product description, image, price. I have two auction templates already, one is the design I want and the other contains the tokens for the script. The script already does most of this but needs tweaking by someone to make it work for me. Anyone fancy it? Jean
