Question

How can I get the value of variable defined in abstract class that is changed in instance of a class that extends it, through a function that was defined in abstract class? The following code should help to illustrate my problem:

Abstract class:

abstract class Kontroler {
    private $pogled;
    function __construct(){
    }
    public function pogled(){
        return $this->pogled;
    }
    abstract function defolt();
}

Class that extends Kontroler:

class E404 extends Kontroler{
    function __construct (){
    }
    function defolt(){
        $this->pogled = 'aplikacija/viewsi/404/404.v.htm';
    }
}

My problem is that I change the value of $pogled inside an instance of the E404 class, but when I call $instanceOfE404->pogled(); PHP returns value of null which is value of $pogled defined in abstract class. Why is this?

Answer 1

private in parent will remain private in the parent – child classes don’t see it. Create a getter function or make it protected.
