URl

And this is not normal?

You can put something like

PHP Code:

public function article ($param_one, $param_two = NULL)
{
  if(!is_null($param_two))
  {
    //do whatever redirect you want
  }
  // else do what you need to do
} 


Or you can simply find out if the number of parameters are bigger than what you need with func_num_args().
