Sometimes, you may want to know what kind of browser is connecting to your web site. Actually such kind of information is usually stored in $_SERVER.  Below is the reference:

  1: <?php


  2:     $useragent = $_SERVER ['HTTP_USER_AGENT'];


  3:     echo "<b>Your User Agent is</b>: " . $useragent; 


  4: ?>
