Good day guys!
Just want to ask the difference of use outise the class and use inside the class ? I have also googled it, but my question doesnt match an answer.
Example:
namespace App\Http\Controllers\Auth;
use Validator;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\ThrottlesLogins;
use Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers;
use Auth;
use Illuminate\Http\Request;
class AuthController extends Controller
{
use AuthenticatesAndRegistersUsers, ThrottlesLogins;
protected $redirectTo = '/';
/**
* Create a new authentication controller instance.
*
* @return void
*/
public function __construct()
{
// Some Code
}
When you define a class, it can only have access to other classes within its namespaces. Your controller for instance is defined within the following namespace.
namespace App\Http\Controllers\Auth;
So to use other classes, you need to import them from their own namespaces so you can access them. e.g.:
use Illuminate\Foundation\Auth\ThrottlesLogins;
If you have javascript ES6 experience, it's a little bit similar to import. When you import a package, the default namespace is /node_modules. To import your own files, you need to sort of namespace them by giving the file location like
import '../containers/index.js'
Back to Laravel. Now that you have imported the ThrottlesLogins, which is actually a trait, now inside the class you use it to expose all of the methods inside.
use Illuminate\Foundation\Auth\ThrottlesLogins; //import
public class AuthController
{
use ThrottlesLogins; //exposes all the methods inside
...
public function login()
{
...
//login failed
$this->incrementLoginAttempts(); //defined in ThrottlesLogins Trait
}
}
From the example above, you have direct access to incrementLoginAttempts(), which is defined the ThrottlesLogins.
