Laravel - Session - Retrieving Data

There are two primary ways of working with session data in Laravel: the global session helper and via a Request instance. First, let's look at accessing the session via a Request instance, which can be type-hinted on a route closure or controller method. Remember, controller method dependencies are automatically injected via the Laravel service container:

    
    session()->get('key');
    
            //
        }
    }
	

When you retrieve an item from the session, you may also pass a default value as the second argument to the get method. This default value will be returned if the specified key does not exist in the session. If you pass a closure as the default value to the get method and the requested key does not exist, the closure will be executed and its result returned:

    
    $value = $request->session()->get('key', 'default');
    
    $value = $request->session()->get('key', function () {
        return 'default';
    });
