That's backwards.  <?php ... ?> is an SGML processing instruction, and
the PHP is its content.

[It's typically better not to inline stylesheets like that, but it's
still good to have hooks for special treatment of element content in
SGML-ish modes.]

The Emacs maintainers don't seem to be interested in contributed support
for PHP or multiple major modes since I was involved, but see
<URL:http://www.loveshack.ukfsn.org/emacs/> for both.  The PHP mode
doubtless needs work, but doesn't have the lexical problems people
complain about with others.  There's a simple html-php multi-mode based
on multi-mode.el.  I haven't had time to make it work with nXML mode.
