========================================================================
USAGE:
========================================================================
include("PHPClientSniffer.php3");
// to use current HTTP_USER_AGENT string
$is = new sniffer();
// to use OPTIONALLY SUPPLIED HTTP_USER_AGENT string
$is = new sniffer("Mozilla/5.0 (Windows; U; Win98; en-US; m18) Gecko/20001209");
** This call must be made before any HTTP HEADERS are sent.
========================================================================
USER DEFINABLE VARIABLES

$CHECK_FOR_COOKIES = true/false
Defines whether or not the Cookie Checking Routine is active. If
it is set to FALSE, the $is->COOKIES variable will return FALSE.

========================================================================
HISTORY:
========================================================================
Saturday, December 16, 2000
+ Konqueror HTTP_USER_AGENT String tested and working
+ Initialized $OP5 and $OP5up as FALSE
+ Pending : sniff of Win2k and JS Versions of Konqueror, etc...
Thursday, December 14, 2000
+ constructor now accepts optional HTTP_USER_AGENT string
+ Opera 5.0 will report as supporting JavaScript 1.3
+ Added Opera 5 Quick Checks
$is->OP5
$is->OP5up
+ Added support for KDE Konqueror Browser (untested)
***NOTES
This is not yet tested, but should at least detect the browser
(assuming it used a standard HTTP_USER_AGENT string.)
Anyone that can send a UA string to me would be doing me a great
service. Also, a mention on the actual version of JavaScript that
is supported by this browser would also be welcomed.
Thursday, September 21, 2000
+ Added Check for Lynx browser ($is->LYNX)
***NOTES
Lynx does not have informative User Agent strings
by default. The most you can get out of a default
User Agent string for Lynx is the Browser Name and
Major and Minor versions.
Wednesday, September 20, 2000
+ Added QuickTests
Wanna know if it's Netscape 4 or IE 4+?
Just check if($is->NS4 || $is->IE4up)
+ fixed $is->LANGUAGE detection routine
+ fixed $is->COOKIES check in Netscape and IE
Friday, September 01, 2000
+ Added HTTP_ACCEPT_LANGUAGE support
$is->LANGUAGE Array
Wednesday, August 31, 2000
** This is a maintenance release. You do not need to replace
version 1.1.0 with version 1.1.1 unless you really want to.
+ Shortened the Cookie Check Routine.
Replaced multiple lines with one line of code.
+ Added $CHECK_FOR_COOKIES user definable variable.
default value is TRUE.
Wednesday, August 30, 2000
+ Added Cookie Check
+ Renamed $is->NAME to $is->BROWSER
