but for php-mode.el. The php-mode I am using/distributing is derived 
from c-mode. It uses c-indent-line. That works in many circumstances but 
not all.

A rather annoying indentation is the following

   for (;;) {
    }

This happens only if the for-loop is on top level, but that happens all 
the time in PHP. Maybe that little thing could be changed in 
c-indent-line? Or maybe someone can help me a bit to fix this in 
php-mode.el?

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superseded 5.28 in summer 2003).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.  ;-)

Well everyone knows my bug reporting skills ;-)

Yes, you are right, but I actually hoped that you should guess the right 
things.

Thanks, that helped. But now I have one of my favourite questions I 
seldom ask: How do I make a local hook so much nil so that the global 
hook is not run?

I have tried to contact the author, Turadg, but he has not replied (yet).

I have done a bit of work on it, but not very much since I do not 
understand most of it.

I have uploaded the slightly changed version here:

   http://ourcomments.org/Emacs/DL/elisp/

Otherwise it is part of nXhtml. There are some problem with my webhost 
right now so it may be difficult to retrieve it. Mail me if you want it.

If you want to have a look at it it would be nice. I think that there 
can be some interest in it again, especially when used in nXhtml (or 
something similar perhaps).

Sorry, I can't parse that (but I do understand about writing foreign
languages).  Which local hook, which global hook?  When do you not wan't
which global hook to run?

It might well me that he (?she) has simply lost interest and given up on
the project.  I hope you get an answer sometime, though.

Where's that little word "yet"?  ;-)

Well, I'm struggling a bit to keep up with everything on CC Mode, so I'm
not really in a position to take on anything extra.

I want to set c-special-indent-hook to nil locally in the buffer and I 
do not want to run the global hook then. Is the global hook still run 
when I set the local hook to nil? I believe it is not run, but I am not 
sure.

Ok, thanks, I see. You have already helped a lot by telling about the 
c-special-indentation-hook and the different styles.

Ah, right!

c-special-indent-hook is already buffer local - try doing C-h v on it in
a CC Mode buffer.  Hmm.  The CC Mode manual should perhaps say this on
the page "Other Special Indentations".  [But after the release. :-]  Just
as a matter of interest, the only function CC Mode itself puts on this
hook is c-gnu-impose-minimum, and that only for "gnu" style.

For other hooks which aren't buffer local, I suppose you could do
something like this:
(make-local-variable 'foo-mode-hook)
(remove-hook 'foo-mode-hook 'bar)

Read the Elisp manual's section about Hooks.
The local hook contains a special entry t which means "run the global hook".
So if you remove the t, the local hook will ignore the global hook.
E.g. if you set the local value to nil, nothing is run.

Ah, thanks. That was what I was looking for.
