From the pdflib manual...
key: Specifies the name of the parameter
doc: a valid PDF document handle retrieved with PDF_open_pdi()
page: A valid PDF page handle (not page number!). For keys which are not page-related page must be -1
Example:
$numPages=pdf_get_pdi_value($p,"/root/Pages/Count",$input,0,0);
