Concatenating PDFs in PHP

I've got a grip of PDFs that I need to combine into one using PHP. Googling around gives me very little that seems like a reasonable solution. The best thing I can find is to use exec() and pdftk but that's just ugly. Does anyone know of a more elegant solution tha开发者_开发问答t doesn't involve me shelling out all the money on the planet for some non-free lib?

Would FPDF AND FPDI work?

Make sure you have FPDF 1.6. This is what I tested with.

You could utilize a PHP/Java bridge to get access to iText.

Actually, the homepage of the bridge component has an example with concatenation of PDFs.

Not sure if there is a pure PHP-based solution, because exec() is really not that ugly as you might think. As an alternative for pdftk you can use Ghostscript:

gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=merged.pdf header.pdf example.pdf
