如何在IE9中从PHP获得完整的扩展UserAgent

Question

in IE9 The command $_SERVER['HTTP_USER_AGENT'] in php returns only the short UA string

and in JavaScript I can get the extended UserAgent with navigator.userAgent property

Is there a way to get the full extended UserAgent in PHP from IE9?

the purpose is to get the strings i have put in the regitry: HKLM\Software\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent\Post Platform the extended UserAgent contain the strings from regitry.

Answer 1

I don't think it gets sent with the headers, only way would be to access

navigator.userAgent

with javascript and push it to your server with AJAX.

EDIT

Or, use PHP's getallheaders() function to check all the headers sent with a request.
