You could probably use something like

<FilesMatch \.php.+$>
Order allow,deny
Deny from all
</FilesMatch>

(or something similar with <LocationMatch>) as long as you don't have
any .phpfoo extensions.

But you seem to have identified a significant problem with using smbfs
in combination with apache, and I wouldn't be confident using that
unless I was sure there weren't any other similar problems.  I would
start by contacting the smbfs developers and asking them about these
types of issues.  When run under windows, apache is aware about all
the funky ways that you can access the same files under different
names.  If smbfs is extending all those onto unix, then it could
create serious problems, because apache has no way of knowing about
it.
