[nycphp-talk] relative newbie needs installation help

On a 4.1.2 install of PHP, I turned register_globals = On in php.ini
and stopped/started apache.  Voila, $HTTP_USER_AGENT is found.  So, you
might not be getting the proper setting of register_globals, and even
in 4.2.x this should still work.

However, I would move away from this, since depending on globally
scoped variables and register_globals is being deprecated quickly.
For this situation, get_browser() may be the way to go.
