The error message means exactly what it says: "pdf_open_file() expects exactly 2 parameters, 1 given"

You need to give it a file name as a second parameter.

See: http://php.net/manual/en/function.pdf-open-file.php

Aside, the documentation also states that pdf_open_file is a deprecated function, so you should be using: http://www.php.net/manual/en/function.pdf-begin-document.php
