Here was the hardest GSoC week ! I wrote a big part of the PDF output and both the themes "phppdf" (each PHP manual part in a file) and "phpbigpdf" (a big PDF file with all the sections).
Examples: Installation & Configuration chapter - Full Manual
* PDF Table of content
* URL links
* internal links
* admonition paragraphs (tips, note, example, warning ...)
* tables (not finished)
* basic stuff (font/style/color changing, auto line wrap, line jumps, auto newline, ...)
If I'm good with tables, this output may be released the next week !
