Answer 2

PHP's get browser method will return the user agent string. All IE 10 browsers will contain MSIE 10.0 in this user agent.

Answer 3

The function get_browser() may be used for feature detection.

If you really want to only know the user's browser version you can look at the $_SERVER['HTTP_USER_AGENT'].

A word of caution: although most users won't do this, it is possible to send a different user agent string to the server which might be done to e.g. protect ones privacy. If someone wants to go as far as sending you a user agent to be able to use your website though they'll probably know how to deal with any bugs that may come up.

As a side question, what is the reason you're trying to limit your audience to IE 10 and up? Why not use a library such as Modernizr to fill in functions you might be missing in IE 9?

EDIT: Some info regarding the IE 10 user agent string. You will want to read that so you know what to match your $_SERVER['HTTP_USER_AGENT'] against
