Beta - but working - code for a new and extensive Session Library.

Code:

function check_activity(){
  // it selects the field nick (which is the only one to be displayd) and then it filters for 1 day or less in age of activity. after that, it filters for 5 minutes or less in activity.
  // first you need to filter away the other days, or your script might get fooled to think that yesterdays login was todays.
  // SELECT nick FROM `users` WHERE TO_DAYS( NOW( ) ) - TO_DAYS( last_login ) <=1 AND DATE_FORMAT( CURRENT_TIMESTAMP( ) , '%H%i' ) - DATE_FORMAT( last_login, '%H%i' ) <=5 ORDER BY `nick` ASC;
}

/**
  * Get the number of online users
  *
  *   This is not 100% accurate. It depends on how often the garbage collector is run
  *
  * @return integer approximate number of users currently online
  */
function get_users_online(){
  // counts the rows from the database
  $result = $CI->db->query('SELECT COUNT(session_id) as count FROM ' . $this->tablename . '');
  // return the number of found rows
  return $result["count"];
}

/**

function setFlash($flashMessage, $layout = 'default', $params = array(), $key = 'flash'){
