Could you do a few things to help me diagnose this, please:

(i) Tell me about this PHP Mode.  Where do I find the PHP Mode that you
are using?  Who maintains it?  (Yourself, perhaps?)  It doesn't seem to
be part of Emacs 22 itself.  The information you've posted says "Major
mode: C/l", which isn't "PHP Mode".  How does php-mode work, here?
[Note: I don't know PHP, so be gentle on me, please!]

Could you be more specific about what you've found here, please.  What
exactly have you found C Mode doing?  What version of CC Mode were you
using before which seemed to work all right? 

(iii) Could you post a dump of CC Mode's configuration.  You get this
with C-c C-b (or M-x c-submit-bug-report).

In that little code snippet, could you please do C-u C-c C-s on each
line, to dump CC Mode's idea of each line's syntax, then post the
results.

"<" and ">" are nasty tokens in C-like languages.  They can appear as
"i < 10", "#include <stdio.h>" and in C++ templates.  It could be that
the PHP "<?" is getting confused with one of these other uses.

Looking forward to hearing from you again,
