  class carA {
  static private $color="red";
  public static function size (){return "big"}; 
  
  
} 

class carB { $color private $color =" black" ;
              public  function size (){return "small"}; 
            //to access a static property to a public function in the same class =>
              static private $price= 3000; 
           public function price(){ 
            return self::$price;
              
            }
            


           }

$carOb = new carB(); 
echo $carOb->color;//output=>black;
echo $carOb->size();//output=>small;
echo $carOb->price();//output=>3000;



//to access to the static( property and methodes) className::propName/methodeName
