Laravel 5: Accessing the Service Container With app

The app function provides access to the "Illuminate\Container\Container" instance. Because Container is a singleton, any call to app() will return the same Container instance. The app function can also be used to resolve registered dependencies from the Service Container instance.

#Signature

The signature of the app function is:

1function app(
2    $abstract = null,
3    array $parameters = []
4);

#Example Use

For example, to return an instance of the "Illuminate\Auth\AuthManager" class (the class behind the Auth facade), invoke app with the auth argument:

1// $authManager will be an instance of
2// Illuminate\Auth\AuthManager
3$authManager = app('auth');

The previous example would be equivalent to resolving the Service Container itself and invoking the make method:

1$authManager = app()->make('auth');
