How do I get a PHP class constructor to call its parent's parent's constructor?

Question

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

//         


        

Answer 1

// main class that everything inherits
class Grandpa 
{
    public function __construct()
    {
        $this->___construct();
    }

    protected function ___construct()
    {
        // grandpa's logic
    }

}

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

class Kiddo extends Papa
{
    public function __construct()
    {
        parent::___construct();
    }
}

note that "___construct" is not some magic name, you can call it "doGrandpaStuff".

Answer 2

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 not a bug, it works that way in php
        Grandpa::__construct();
    }
}

Answer 3

Ok, Yet another ugly solution:

Create a function in Papa like:

protected function call2Granpa() {
     return parent::__construct();
}

Then in Kiddo you use:

parent::call2Granpa(); //instead of calling constructor in Papa.

I think it could work... I haven't test it, so I'm not sure if the objects are created correctly.

I used this approach but with non-constructor functions.
