• new feature
• BC break? no (InjectExtension::getInjectProperties changed - but it was marked as internal)

I also added new method getByTypeAndTag (container + autowiring) so $throw can be always as last parameter, otherwise it would be getByType($type, $throw, $tag).

Now it's possible to have multiple services of the same type and inject them by tag with #[Inject(tag: <tag>), it's also possible to use in constructors.

Only rule is that one of those multiple services needs to have tag default, and that service will be injected if no tag is specified (or if you specify default). I have considered also to inject service with least amount of tags or with no tags, but this can lead to unpredictable behavior when more tags are added in the future.

This allows to work with interfaces and requiring specific services, some examples:

• cache implementations
• doctrine connections
• flysystem implementations
• monolog channels

final class MyService
{
	#[Inject('slack')] 
	public LoggerInterface $slackLogger;

	public function __construct(
		private Connection $connection,

		#[Inject('secondary')] 
		private Connection $secondaryConnection,

		private Cache $cache,

		#[Inject('asset')] 
		private Cache $assetCache,
	) {}
}
