The problem you're getting is that your web-server interprets the
request as a request for a normal file and just sends it - in effect,
you're not outputting the postscript file, you're just sending the
.php file. Normally, you'll only get your php executed if the file
requested is a .php or .phtml - unless you've changed your server
config.
Try creating a serveps.php that uses the header("Content-Disposition:
attachment; filename: 'serveps.ps'") instead, see if that helps you.
