You may check it out for yourself:

	if(in_array($name, $this->m_names))
		{
			$this->m_rules[$name][] = $rule;
			var_dump($_SESSION[$name]);
			return $_SESSION[$name];

		}

If the session is not initialized or the session variable has not been
set before, it will print NULL.

You'll find comprehensive information about PHP sessions on
