downloading files

I've only been playing with Apache/PHP for a couple of weeks so have mercy if this is a dumb question. I'm providing a browsable frontend to a data archiving system to allow users to retrieve files from an off-line storage system. At the interesting point in the transaction, the user selects a file by clicking on its name to execute a link that looks like: http://hostname/getfile.php?someinfo?filename. I've written the getfile.php script to get the file from the backend to the web server machine, and then hand it to the browser using: ... // get file from backend into tmp directory on web server ... header( "Location: http://hostname/tmp/$filename" ); The question I have is how can I control the downloaded file's name. Instead of being named, for example, demo.ppt, it is saved by the client's browser as getfile.php. Is there a completely better way to be doing this?
