You could also use mod_rewrite to achieve this goal -- but you'd need to
be the server administrator . . .

I also recommend that you create a symlink
   ln -s download.php download

Then add a line to the .htaccess file in the same directory, which 
forces PHP to interpret that download symlink:
  <Files "download">
        ForceType application/x-httpd-php

Instead of passing the file name like this: "download?myfile.txt", make 
it look like a directory:
Instead of:

Then, use the $_SERVER['PATH_INFO'] variable in download.php to get the 
filename. This makes it quite transparent to the end-user and obeys Tim 
Berners-Lee's rule that "cool URLs don't change".

Good luck!
