title: PHP - Display messages to certain browsers
body: <p>I've searched for this and everything I find is way more than I need.  I've done this in JavaScript before, but I would really prefer using PHP.  How would I go about displaying a message to my visitors, depending on which browser they're using?  </p>
  
  <p>Example:</p>
  
  <p>IE User would see:  "You're using Internet Explorer"</p>
  
  <p>Firefox User would see:  "You're using Mozilla Firefox"</p>
  
  <p>I'm not exactly sure if there are other major browsers besides IE, Firefox, Chrome, Safari, and Opera.  But I would at least want to have a message directed to each one of those browsers individually.  Thank you.</p>
