Browser class

Identifies the user’s Operating system, browser and version
by parsing the HTTP_USER_AGENT string sent to the server

Typical Usage:

require_once($_SERVER[‘DOCUMENT_ROOT’].’/include/browser.php’);
$br = new Browser;
echo “$br->Platform, $br->Name version $br->Version”;

For operating systems, it will correctly identify:
Microsoft Windows
MacIntosh
Linux

Anything not determined to be one of the above is considered to by Unix
because most Unix based browsers seem to not report the operating system.
The only known problem here is that, if a HTTP_USER_AGENT string does not
contain the operating system, it will be identified as Unix. For unknown
browsers, this may not be correct.

For browsers, it should correctly identify all versions of:
Amaya
Galeon
iCab
Internet Explorer
For AOL versions it will identify as Internet Explorer (AOL) and the version
will be the AOL version instead of the IE version.
Konqueror
Lynx
Mozilla
Netscape Navigator/Communicator
OmniWeb
Opera
Pocket Internet Explorer for handhelds
Safari
WebTV

I’m completely unfamiliar with this and was wondering if someone could help fix these deprecated errors
