I know you use that trick a lot, but for me assert(null === 'test'); doesn't throw an exception.

Your statement might be misleading.

In fact, I think it will not throw an exception in most cases. I use assert() when I want my IDE to know what I expect when I can't use type hints.

See https://www.php.net/manual/en/function.assert.php

Hey Julien,

Hm, the assert(null !== $chartBuilder) should throw AssertionError when $chartBuilder = null, see https://3v4l.org/s8TRL

The same is true for your example with assert(null === 'test'). I'm not sure why it's not throwing an exception for you, probably something is changed in the php.ini? What version of PHP do you have? The default PHP config should throw an exception, and if you don't see it, here're some possible reasons why:

Assertions are disabled in your PHP configuration: If assertions are disabled (zend.assertions directive set to 0 in php.ini), then all assert() calls are ignored, and no AssertionError will be thrown.
Assert options are configured differently: The behavior of assertions can be controlled via assert_options() function. If the setting ASSERT_ACTIVE is set to false, assertions are ignored. Check if assert options are set to their default values.
Error reporting settings: If your PHP installation suppresses error reporting, you might not see the AssertionError even if it's thrown.

Cheers!

I have a kind of question. How about the Required attribute?

// ...
use Symfony\Contracts\Service\Attribute\Required;
use Symfony\UX\Chartjs\Builder\ChartBuilderInterface;
// ...

class DashboardController extends AbstractDashboardController
{
    #[Required] public ChartBuilderInterface $chartBuilder;
    // ...
}

Personally, I prefer that way to inject services.
Pros:

short and straightforward
don't need to touch ctor signature (or can be promoted as well)
simple capability to mock dependencies in tests

Cons:

can't be readonly and since it's public - theoretically can be reassigned (I didn't face yet such things)
implicit dependencies, when you'd like to instantiate object manually (rare case)
maybe some overhead because of reflection?

Have you other thoughts about DI via ctor arguments vs Required attribute?

Hey Yaroslavche,

Interesting idea, though as you said it's public property so it cannot be read-only and probably violates some SOLID principles. Also, in case you inject it directly into the method name - it's a method dependency. But if you make it a property - it probably would mean it's a class dependency now, so it seems you increase its scope.

But in general, it is just a matter of taste and mostly depends on the specific use case. :)

Cheers!
