<?php

// I declare that MyService needs two Parameters, one: an object, two: a scalar value
class MyService {
    public function __construct(AnObject $service, $value) {
        $this->service = $service;
        $this->value = $value; // pretty common right?
    }
}



// Now, in my controller, I simply want to be able to DI the MyService object automatically, but it requires a value, so I can't do that
// instead, I'll either have to use a SETTER (which I dont' want to, because my library NEEDS $value as a constructor parameter and I'm not changing it), or a factory. Here's what I'll have to do with a factory:

class MyServiceFactory {
    public function build($value) {
        return $provider->make(MyService, [':value' => $value]);
    }
}

// Now I DI this service factory into my controller...

class Controller {
    public function indexAction(MyServiceFactory $factory, Request $req) {
        $userSuppliedValue = $request->getValue('postValue');
        $factory->build($userSuppliedValue);

        // Note how the $userSuppliedValue, that MyService needs as a constructor parameter, ISNT KNOWN until INSIDE the function I'm already asking it to be DI'd into?
    }
}
