note 20836 added to function.eregi

I want to get OS and it's version out of $HTTP_USER_AGENT if(eregi("windows nt [0-9]{1,2}.[0-9]{1,2}",$HTTP_USER_AGENT,$match)) { $os = $match["1"]; $version = $match["2"]; } This code i IMO pretty nice, but there are some bugs: how do i make difference of which matches match[1] and which matches match[2] ?!? PS, I got the idea from a post (kavandi@alias.net.au) in get_browser section (http://www.php.net/manual/en/function.get-browser.php). Can someone explain it to me? -- http://www.php.net/manual/en/function.eregi.php http://master.php.net/manage/user-notes.php?action=edit+20836 http://master.php.net/manage/user-notes.php?action=delete+20836 http://master.php.net/manage/user-notes.php?action=reject+20836
