Downloading Files from server

[netfrugal]

I usually just right click a link to a PDF, Word doc, etc... and choose "file save as"

Otherwise, a new browser window opens and displays the document in the browser.
Is there a way to automatically download the file when clicking the link? Is this a header() issue?

$file = 'file_to.download';

header ('Content-disposition: attachment; filename="'.addslashes($file).'"');
header ('Content-length: '.filesize ($file) );
readfile ($file);
