<?php
  //Explanation and features
  //1- we can call the static methode  and  property without creating instance
  //from the class  => syntax to call is : classname::methodename(),ore propName.
  // static property save the new value in the function . 
  
  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
echo carA::$color; //output is : red;
  echo carA::size(); //output is : big;
