the order is important, because opera must be tested first, and ie4 tested for before ie general
same for konqueror, then safari, then gecko, since safari navigator user agent id's with 'gecko' in string.
note that $dom_browser is set for all  modern dom browsers, this gives you a default to use, unfortunately we
haven't figured out a way to do this with actual method testing, which would be much better and reliable.
 
Please note: you have to call the function in order to get access to the variables, you call it by this:
 
browser_detection('browser');
 
then put you code that you want to use the variables with after that.

you would call it like this:
 
$user_browser = browser_detection('browser');
 
if ( $user_browser == 'opera' )
{
	do something;
}
 
or like this:
 
if ( browser_detection('dom') )

	execute the code for dom browsers
}
else

	execute the code for non DOM browsers
}
 
and so on.......
