Laravel 5.4 Higher Order Messaging

Question: Why do the old approach returns the right value see result old approach and the new HOM approach returns the whole collection?

Role Model

class Role extends Model {
    public function getName() {
        return $this->name;
    }
}

Controller

$roles = Role::all(); // get all roles to test

// old approach
$roles->each(function(Role $i) {
    var_dump($i->getName()); 
});

// new approach (HOM)
var_dump($roles->each->getName());

If I implement the new approach with higher order messaging it returns me the whole Collection, if I use the old one I get the right result.

Result old approach

string(11) "Application"

string(6) "System"

string(7) "Network"

string(7) "Manager"

Result new approach

object(Illuminate\Database\Eloquent\Collection)#196 (1) {

  array(4) {
[0]=>

each just iterates over the collection, it doesn't actually return anything. If you want it to return the value of getName() for each iteration then you could use map e.g.

dump($roles->map->getName());

Hope this helps!
