Thank you for fast answer
I tried and it worked, i just did like this:
$str_pdf = file_get_contents("$pathtopdf");
echo $str_pdf;
Is this right? How can I set the right header?
When I did this the pdf-file that I downloaded got the same name as
the php-file that the script is in, how can I rename it to something
else?
