Proposal: Way to use global

[rustamwin]

What steps will reproduce the problem?

Getting container globally

What is the expected result?

this is useful for functions
e.g: Container::getInstance()

What do you get instead?

That would result in using it as service locator and that is exactly what we've tried to avoid.

Hi, why not use delegate with a reflection class instead of injecting the entire container.

Example:

<?php declare(strict_types=1);

$container = new League\Container\Container;

// register the reflection container as a delegate to enable auto wiring
$container->delegate(
    new League\Container\ReflectionContainer
);

$foo = $container->get(Acme\Foo::class);

var_dump($foo instanceof Acme\Foo);           // true
var_dump($foo->bar instanceof Acme\Bar);      // true
var_dump($foo->baz instanceof Acme\Baz);      // true
var_dump($foo->bar->bam instanceof Acme\Bam); // true

@rustamwin I think it's better to get container instance to where functions are declared and pass it there via use ($container). Is it possible?

[rustamwin]

@samdark I mean something else, global functions are declared here. I want declare new function something like this:

if (!function_exists('alert_success')) {
   function alert_success($message, $remove = false) {
       Container::getInstance()->get(FlashInterface)->add('success', $message, $remove)
   }
}

Is this a temporary solution?

[samdark]

No, why? I want to make accessing container globally (except maybe these functions) a hard enough task so people won't abuse it without thinking.
