This is for you Personoid ;P

Class is quite unnecessary for only two functions :p Regardless, looks to be working.

Rofl. Nice timing i was thinking about this for some hardware i have thats programmable. Hard to explain. I can explain it later on MSN if you want.

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();

$info = new ua();

r u srs...?

Edit: didn't work as of yet. I'll mess with it more in a bit.

Lol, () actually isn't needed if there is no variables you need to pass through to the constructor method. Unfortunately, looking at that class, it requires a user agent in the constructor. In which case, the following would work:

$info = new ua( $_SERVER['HTTP_USER_AGENT'] );

I probably should have noticed that. I kept wondering what __construct was.
Thanks. I've never really worked with classes.

O: I just started OO PHP. Should grasp it quickly, seeing as it isn't much different than C++.

OOP ;] And yeah it's fun stuff.
