Hello again! Simple question (hopefully) just for understanding: For the dependency providers … would there be a downside passing the Container $container variable to each adding-function as „by reference”? I think i already heard a good reason against, but i really can’t remember … Thanks a lot 🙂

it’s a class, so passed by reference by default

you mean just changing instead of returning and overriding in the calling method, right?

what is it you want to achieve?

if mean instead of
…
$container = $this->addStore($container);
…
do
$this->addStore($container);
….0 -
and in the function omit the return value
0 -
protected function addStore(Container $container)
{
$container[static::STORE] = function (Container $container) {
return Store::getInstance();
};
}instead of
protected function addStore(Container $container) { $container[static::STORE] = function (Container $container) { return Store::getInstance(); }; *return $container;* }

I got the question from a colleague regarding this and i want to give him a plausbile answer 🙂 … so he asked why not using the “short” way instead of doing unnecessary assertions all the time …

Hi Ingo, both ways work but we decided to always use explicit input and output parameters for methods. In case a parameter is modified inside of a method but not returned then the signature of the method would be misleading. That’s called an
inout
parameter and I would call it a bad practice.0
