Question

I need to have a class constructor in PHP call its parent’s parent’s (grandparent?) constructor without calling the parent constructor.

// main class that everything inherits
class Grandpa 
{
    public function __construct()
    {

    }

}

class Papa extends Grandpa
{
    public function __construct()
    {
        // call Grandpa's constructor
        parent::__construct();
    }
}

class Kiddo extends Papa
{
    public function __construct()
    {
        // THIS IS WHERE I NEED TO CALL GRANDPA'S
        // CONSTRUCTOR AND NOT PAPA'S
    }
}

I know this is a bizarre thing to do and I’m attempting to find a means that doesn’t smell bad but nonetheless, I’m curious if it’s possible.

Answer 1

The ugly workaround would be to pass a boolean param to Papa indicating that you do not wish to parse the code contained in it’s constructor. i.e:

// main class that everything inherits
class Grandpa 
{
    public function __construct()
    {

    }

}

class Papa extends Grandpa
{
    public function __construct($bypass = false)
    {
        // only perform actions inside if not bypassing
        if (!$bypass) {

        }
        // call Grandpa's constructor
        parent::__construct();
    }
}

class Kiddo extends Papa
{
    public function __construct()
    {
        $bypassPapa = true;
        parent::__construct($bypassPapa);
    }
}
