I have data in a MySQL database. I am sending the user a URL to get their data out as a CSV file. I have the e-mailing of the link, MySQL query, etc. covered. How can I, when they click the link, have a pop-up to download a CVS with the record from MySQL ... to get the record already. I just don't see how to have PHP create the CSV file and let them download a file with a .csv extension.
