A newbie silly question: get_browser()???

Hya all. I am a newbie. I am trying to build a php page that check the level of your browser and redirect to a download page if your browser is of the wrong generation (i.e. does not support HTML 4.0 and CSS). Furthermore, it should check your prefrences (javascripts enabled/disabled, java enabled/disabled) in order to send a warning to the user ("warning: you could experience some minor problem". I am thinking of using the get_browser() function, but i do not know how it really works ... (shame on me!!). I have tryed some experiments, but i have not been able to obtain ANY result .... :-( Any suggestion????
