OP SYS with selfdefined name?

[kaits]

$_SERVER['HTTP_USER_AGENT']
this shows something like that:
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)

but how now to show not MSIE 6.0 but Internet Explorer 6 or Netscape 4 etc and how to get OP systems like Windows 98, Windows XP etc ?

 

[THE REAL TOOLKIT]

You can use an expression to look if the code contains e.g. "MSIE 6.0"
and then print "Mircosoft Internet Explorer Version 6.0"
