      header("Content-Type: text/html; charset=utf-8");
      if(!isset($_GET['action']))
      {
          $_GET['action'] = "home";
      }
  
  echo("&lt;!DOCTYPE HTML&gt;");
      echo("&lt;html&gt;");
          echo("&lt;head&gt;");
              echo("&lt;title&gt;Bug Tracker -  ");
              echo($_GET['action']);
              echo("&lt;/title&gt;");
              echo('&lt;link rel="stylesheet" href="common.css" /&gt;');
          echo("&lt;/head&gt;");
          echo('&lt;body&gt;');
              require("action.php");
