Access functions of other classes in SlimPHP

I have to different classes in my Slim PHP framework, named OrderController & AddressController. I want to access some function of AddressController inside OrderController to reduce code redundancy.

But can't get a way to do it, I got how to do it in pure PHP setup, but how to do it in Slim PHP framework?

The PHP way to do this is as follows:

class A {
    private $xxx;

    public function __construct() {
        $this->xxx = 'Hello';
    }

    public function getXXX() {
        return $this->xxx;
    }
}

class B {
    private $a;

    public function __construct(A $a) {
        $this->a = $a;
    }

    function getXXXOfA() {
        return $this->a->getXXX();
    }
}

$a = new A();
$b = new B($a);

$b->getXXXOfA();

How to achieve this dependancy injection in Slim?

2 solutions come into mind:

-1-

You could also try to have the common functionality in a separate Trait.

-2-

I won't do the new SecondController($container) inside the constructor of the FirstController unless you need it at every controller-hit. I like lazy loading, so it will load only when needed.

After a lot of reseach I finally manage to get a solution! Posting it here so if anyone in future might get help from it:

class FirstController 
{
    protected $container;
    protected $db;
    protected $view;
    protected $second;

    // constructor receives container instance
    public function __construct(\Interop\Container\ContainerInterface $container) {
        $this->second = new SecondController($container);
        $this->container = $container;
        $this->db = $this->container->db;
        $this->view = $this->container->view;
    }

    public function LocalFunction(){
        $this->second->otherFunction();
        //call the functions in other classes as above
    }

}

If your OrderController wants to call a method foo from AccessController, you should think about moving foo somewhere else. That's an good indicator for wrong SRP

There are two possibilities

  1. foo belongs to/is relevant for every Controller and has something to do with controlling: Just move it to the parent class.

  2. foo is relevant to only a few classes: Move it to the class, it belongs to. This could be an helper class, some domain model class, or something else. Maybe you have to intruduce a new class to do this.

If your AddressController and OrderController has same parent class, than move these methods to parent:

class AddressContoller extends Controller {
    public function test() {
        $this->methodFromParent();
    }
}

If not, create new object of that class and call method. Method must be public

class AddressContoller extends Controller {
    public function test() {
        $order = new OrderController();
        $order->publicMethodInOrderClass();
    }
}
