      function request_uri()
      {

      if (isset($_SERVER['REQUEST_URI']))

      {

      $uri = $_SERVER['REQUEST_URI'];

      }

      else

      {

      if (isset($_SERVER['argv']))

      {

      $uri = $_SERVER['PHP_SELF'] .'?'. $_SERVER['argv'][0];

      }

      else

      {

      $uri = $_SERVER['PHP_SELF'] .'?'. $_SERVER['QUERY_STRING'];

      }

      }

      return $uri;

      }

      

      ?>
