If you are having troubles getting the page count make sure you have Root caplitalized correctly.
$numPages=pdf_get_pdi_value($p,"/Root/Pages/Count",$input,0,0);

For keys which are not page-related page must be -1 (in PHP: 0).

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);
