[PHP] File sending?

[Chris]

Hi,
Is it possible to send a file to a browser?
I would like to allow people to download a file, but I don't want to give away the 
path to the file, so a normal link wouldn't work.
I am hoping there is a way to use php to send the file using code, rather than trying 
to first copy the file to a temp dir then give them the link, then worry about 
deleting the temp dir again.

Thanks,
Chris
