  {
    return "Bo!";
  }
}

class Rat extends Monster
{
  public $size = 'small';

  public function scare()
  {
    return parent::scare() . " (runs away)";
  }
}

class Mouse extends Rat 
{
  public $color = 'white';
}

And the output would be:

$rat = new Rat();
echo $rat->scare(); //output: Bo! (runs away)
echo $rat->size;    //output: small
echo $rat->color;   //output: grey
