title: Force users to use Chrome/FireFox instead of IE
body: <p>I have a website build using PHP and HTML. If a user browses my website using IE, I want to display a message saying: "Please use Firefox or Google Chrome" instead of rendering the index page.</p>
  
  <p>Is it possible? If so how could it be done?</p>
  
  <p>Please note I am not that advanced with PHP.</p>
  
  <p>Thanks.</p>
