Question

I have a class which initiates another class, i’m not concerned with having a reference to the object i only need the method and have to pass in new parameters.

class A {
     __set .....
}

class B extends A {
     $anotherA = new A;
     $anotherA->myName = 'stackoverflow';
}

in short i’d like to have class B extend A, init a new instance of A but i don’t want to have to type “new” everytime, i’ve seen the following syntax:

B::A // something like that

but not sure if how to use it or if that would do what i’m trying to do?

Answer 1

I would create the instance of A in B’s constructor, then you can instantiate B using either its constructor or static B::create(), which just acts as a shortcut. You could make the constructor private if you wanted all instantiation go through create().

class A {
    // __set .....
}

class B extends A {
     public function __construct() {
         parent::__construct();
         $anotherA = new A;
         $anotherA->myName = 'stackoverflow';
     }

     public static function create() {
         return new self();
     }
}


new B();
B::create();
