PHP PDF template library with PDF output?

Have you considered using something like XSL:Formatting Objects (XSL:FO)? Basically they're XML documents that are processed and turned into PDFs. Doing string - or better, DOM - replacements within that should be pretty simple. It supports embedding images, links, annotations, etc.

It's not PHP but there are a number of PHP wrappers for it along with ways of using it via exec, etc. Not an ideal but it takes care of the template portion completely. For some more info: http://techportal.inviqa.com/2009/12/16/transforming-xml-with-php-and-xsl/

There's an implementation available as an Apache project - http://xmlgraphics.apache.org/fop/

This is not very practical, but for completeness: If you already have an ODT template, then you might very well retain that as template. Modifying the OpenDocument content.xml and replacing placeholders therein is pretty simple. If so, you could use unoconv or pyodconverter to transform the ODT into a final PDF.

unoconv -f pdf -o final.pdf template.odt

Very obviously this requires a full OpenOffice setup (UNO and Writer) on the webserver. And obviously not every webhoster would go with that! haha. Even if it's simple on any Debian or Fedora setup. The execution speed would probably not be stellar either. But then it might be the cleanest approach, since OOo governs both formats way better than any PHP class ever could.

Pekka,

I looked in to this previously, I think you can use pdftk (a command line utility), to fill in a PDF form using FDF/XFDF data files, which you could easily generate from within PHP. That was the best option I've seen so far, though there may well be a native library.

pdftk is quite useful in general, worth having a look at.
