What is Dependency injection in Laravel?
In Laravel, dependency injection is a term used for the activity of injecting components into the user application. It’s a key element of agile architecture. The Laravel service container is a powerful tool that manages all class dependencies and performs dependency injection.
public function __construct(UserRepository $data)
$this->userdata = $data;
In this given an example, the UserController needs to retrieve users data from a data source(database). So, we can inject a service that is able to recover all users. In this example, our UserRepository most likely uses Eloquent to get user’s data from the database.
