Just as an aside, your bug report could have been a little more
detailed and helpful, for example by saying where you got php-mode.el
from (it isn't part of Emacs 22), and being a bit more precise about the
indentation (you've pictured the "for" starting at column 2 despite
having said "on top level").  It could have been MUCH more helpful by
dumping CC Mode's configuration (C-c C-b).  :-)

However, assuming that the "for" is really at column 0, and that
php-mode.el came from <http://php-mode.sourceforge.net/>

As a pure guess, the indentation of the "}" to column 1 probably comes
from `c-gnu-impose-minimum' which is installed on c-special-indent-hook
for the style "gnu".  If you set a different style (e.g. by C-c .), this
problem might go away.  Or remove it from c-special-indent-hook in
php-mode-hook or one of CC Mode's hooks.

The php-mode.el at SourceForge, when I last looked at it, didn't look
like it was being actively maintained.  The latest release was from
2003, and it didn't appear to have been updated for CC Mode 5.30 (which
superseded 5.28 in summer 2003).

I think that php-mode.el needs a serious amount of work done on it to
bring it up to date with the current CC Mode.  It would probably be
better to wait till after the release to do this.  ;-)
