[PHP] User_Agent - Browser/Operating System Extractor

[Personoid]

Thanks.
Also, I knew my user agent had Windows NT 6.1 but I wasn't sure if it was actually a Windows 7 user agent.
I thought maybe some other factors came into play since my shit's usually jacked up anyway.

Edit: what am I doing wrong with the class?

 $info = new ua;
$browser = $info->getBrowser();
$operating_sys = $info->getOPSystem();
