6. PHP is a server side scripting language. Whatever processing PHP does
takes place BEFORE the output reaches the client. Therefore, it is not
possible to access users' computer related information (OS, screen size
etc) using PHP. Nor can you modify any the user side settings. You need
to go for JavaScript and ask the question in a JavaScript list.
On the other hand, you can access the information that is SENT by the
user's browser when a client requests a page from your server. You can
find details about browser, OS etc as reported by
this request.

You might want to add to this:-
"To see what information PHP can provide look in the manual for $_SERVER."
That way you give people a pointer along the way ....
