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);
