How are you doing
C Object
(
[Name:p:private] = Hello
)

Class p{    Private $name = "";    function __construct () {        $this->name= "Hello";    }    Public Function __set ($name, $value) {        $this, $name = $value;    }    Public Function ShowName () {        echo $this->name;    }} Class C extends p{    function __construct () {        parent::__construct ();         What do you do if you want to change the value of P-class $name (hello) here? $this->name = ' Hello ';    }} $obj = new C (); $obj->showname ();
