class AClass {
    public $x = 13;
    public static $y = 50;
    const PI = 3.14;
    public function f() { return 7; }
    public static function s_f() { return 90; }
}

$object = new AClass();
var_dump($object->x);    // int(13)
var_dump($object::$y);   // int(50)
var_dump($object::PI);   // float(3.14)
var_dump(AClass::$y);    // int(50)
var_dump(AClass::PI);    // float(3.14)
var_dump($object->f());  // int(7)
var_dump(AClass::s_f()); // int(90)

$aclass = "AClass";
var_dump($aclass::s_f()); // int(90)
    

 
/*
run: 
  
int(13) int(50) float(3.14) int(50) float(3.14) int(7) int(90) int(90)
  
*/
