Force Download with the default filename of the actual file

Hi, currently i have a system set which forces people (on most browsers) to save the pdf document in question to disk. When this document saves the default save name is the name of the script rather then the name of the pdf document. Is there a way for me to make the default save name the actual name of the pdf document? here is my code...

@$fileName = "27xSdox/$filedata.pdf";
@$filesize = filesize($fileName);
if($filesize) {
@Header("Content-Length: ".$filesize);
@Header("Content-Disposition: attachment; filename=".$fileName);
@readfile($fileName);
}

thanks

I thought that browsers take the title as a savename.
I'm not sure...

Here's a thread at phpbuilder that might be of some help. Different browsers download differently, and this script takes that into account...
