PDF pain

I THINK I have installed pdflib and compiled it into PHP 4.2.1 OK. At least, configure/make/make install all went OK and it is trying to work. I copied the sample 'Hello World in PDF' script out of Programming PHP (p 234) into a file named pdftest.pdf When I try to access http://localhost/pdftest.pdf, Konqueror tries to open a PDF file but then spits the dummy saying: "Could not open file blahblah.pdf which has type application/x-zerosize. KGhostview can only open Postscript and Portable Document Format files" So it looks like a header problem or something? This raises a few other questions: - Should the PHP script be called pdftest.php or pdftest.pdf? - Does httpd.conf need an AddType directive for pdf files? I've tried a few variations on "AddType application/x-pdf .pdf" etc - Should .pdf be added to the php AddType directive? eg. "AddType application/x-httpd-php .php .htm .pdf Basically, I'm confused. Anyone been there done that? TIA Michael
