Foreach通过laravel中的“name”执行动作静态函数：x

Question

Someone please help me enlighten in LARAVEL !!!

in LARAVEL controller i difine static function like this :

namespace App\Http\Controllers\MyAPI;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
class MyAPIController extends Controller {

    const acceptMethod = ['GET','POST','PUT','DELETE']

    public function handler(Request $request) {
           $acceptMethod = self::acceptMethod;
           $ctrl = new PromotionController;
           $method = $request->method()

         // This is my question :((
          if ($method == 'GET')
              $ctrl::read($request);
          if ($method == 'GET')
              $ctrl::post($request);
          $ctrl::put($request);
          ... 

          //I want to be like this : 
           foreach($acceptMethod as $method) {
              // Not work 
               $ctrl::($method)($request);
           }


    }

    public static function read(Request $request) {
        return something;
    }

    public static function post(Request $request) {
        return ...;
    }

    public static function put(Request $request) {
        return ...;
    }

    public static function delete(Request $request) {
        return ...;
    }

}

And then i must use controll like :

  if ($method == 'get')
      $ctrl::read($request);
  if ($method == 'post')
      $ctrl::post($request);
  $ctrl::put($request);

But i have a array :

and i want to be like this :

 $acceptMethod = ['GET','POST','PUT','DELETE'];   
 foreach($acceptMethod as $functionName) {
    // Not work 
    $ctrl::$functionName($request);
 }

Is there any way to make this possible ??

Answer 1

Use {};

Please, try this inside the loop:

$fn = strtolower($functionName)
$ctrl::{$fn}($request);

You can call a attribute too..

$instance->{'attribute_name'};
