User details

[joaoduraes@yahoo.com]

Hello.

What information can we get from a user using PHP?
I know that javascript can "read" a lot of things, like screen size,
colour depth....and use a few tricks to send that information to the
serrver.

I know that with PHP we can get the user agent of a browser and little
more.
What else can we get with PHP and/or with javascript??


Thanks!!

Anything that is in te $_SERVER array, don't trust it though, it's just
headers the clients send on a request.

One of the nicer and usefull once is for instance HTTP_ACCEPT_LAN GUAGE,
which will by most modern UA's be filled with the language of the OS by
default, or a user defined value. Way better to decide which language to
show then GeoIP stuff, and with a lot less overhead.
