Extraction of PDF properties
Informations
Author: Sacha MPS
License: FPDF
Description
This function extracts the document properties from a PDF file. It works fine with documents
generated by FPDF. It can also work with PDFs made from other generators, but not all.
The get_pdf_prop()
function returns an associative array whose keys are the names of
the properties found in the file (such as Author, CreationDate, Creator, Keywords, Producer,
Subject and Title).
