php documentation template?

Dear PHP webmaster, I'm a member of a MonetDB project, which is an open-source DBMS. Recently we developed a PHP interface for it, and now I'm preparing to write user documentation. I wanted to ask you if there is a template for PHP module documentation available, since I would like to make our documentation look as close as possible to typical PHP site. That would be good for users familiar to your layout/colors etc, and would reduce work if (hopefully) one day PHP team agrees to include MonetDB interface as part of PHP. Thanks in advance for help, Marcin Zukowski
