Can a DI container work like this?

Question

PHP

$sys = new Container();
Next, the class reads the config, where it is written how to create an object, its constructor arguments, etc.
The first time you call a service like

$sys->get(Request::class);
//или по псевдониму как $sys->request

The container will create an object following the rules in the config.
You can dynamically register services through closures

$sys->notInitService = function(Container $c) {
return new NewService($c->get(ServiceArg::class));
}

Can it even work like that? There is a ton of information and articles on the net that are leveled in meaning and it is very difficult to find a clear explanation of DI

Hello.
Of course it can.
Have a look at a good DI implementation - php-di.org/.
Your example would look like this:

$container->set(ServiceArg::class, function(){
    return new ServiceArgImpl();
});
$container->set('notInitService', \DI\object(NewService::class));
