PHP: PDFlib, OOP & Comments

Question

Since PHP 4.0.5 there are functions to dynamically generate PDFs (PDFlib). I have 3 questions to the PDFlib:

1. Is there an OOP class? If not, is it planned in a future version of PHP?
2. Is there a function to add comments to a pdf AND override the old one?
3. Is there an alternative, which is able to do the things above?

Answer 1

In PHP5 there is OOP version on PDFlib. Check it here: http://www.php.net/manual/en/intro.pdf.php As i know, you can't use it full version for commercial purpose. You can try to use FPDF instead: http://www.fpdf.org/
