Using Php is it possible to detect exact OS even if the browser agent

Using Php is it possible to detect exact OS even if the browser agent value is altered?

Here is the case

If someone override Firefox useragent value using “general.useragent.override”

Actual: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:12.0) Gecko/20100101 Firefox/12.0

Override: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_3) AppleWebKit/534.55.3 (KHTML, like Gecko) Version/5.1.3 Safari/534.53.10

$_SERVER[‘HTTP_USER_AGENT’] value will be totally fake. it’s not useful even to detect correct Operating System.

Is there any Php solution in this situation?
Thanks.

    No, it is not possible. The only information you have is that supplied by the User-agent header, and if a user wants to send false information there is nothing you can do to detect it.
