Do you need support for PDF documents with a version higher than 1.4? Check out the new FPDI PDF-Parser!
FPDI is a collection of PHP classes facilitating developers to read pages from existing PDF documents and use them as templates in FPDF, which was developed by Olivier Plathey. Apart from a copy of FPDF, FPDI does not require any special PHP extensions.
Since version 1.2.1, FPDI only supports the 1.6 version of FPDF.
As of version 1.2.1 FPDI can also be used with TCPDF.
FPDI is developed by Setasign - Jan Slabon - and is published under the Apache Software License, Version 2.0.
The usage is very easy: open the document, put a page into a template, and use it like an image!
