For anyone interested, I updated the PHP Documentor snippets and added them to the SVN repos (in PHP.tmbundle). The snippet "phpdoc_u" prints usage and explains the updates I made (i.e. you now use TextMate shell variables to set @author/@copyright defaults). http://macromates.com/svn/Bundles/trunk/PHP.tmbundle/
FYI Matteo : I have an svn account now, so I will help out with any changes needed for the PHP bundle ... as TextMate/PHP evolve. You mentioned you had some other ideas for macros/snippets ... just thought I would add these snippets in as-is, for convenience of distribution. They are always up for improvement or abstraction.
