PHP support questions

I have a few questions related to the PHP support.

First how can I declare include files (require_once, require,
include_once, include) and defines (define(name, value))?

Also I have seen in the changelog 
   http://www.stack.nl/~dimitri/doxygen/changelog.html
in the 1.2.17 changes:
   #  Added initial support for parsing PHP code (thanks to a patch by Jan
      Borsodi). For a PHP file the following additional commands are available:
         \private makes the current item private
         \protected makes the current item protected
         \public makes the current item public
         \privatesection changes to private section(same as private: in C++)
         \protectedsection changes to protected section(same as protected: in 
C++)
         \publicsection changes to public section(same as public: in C++)
         \static changes the current item to static
         \pure changes the current item to pure virtual

But I can't figure how to use the \(private|protected|public)section
commands. 

Thanks,
Christophe
