尝试在SubmitPerformanceController中创建一个新的PrintReportController对象，并直接调用getPrintReport方法。

例如，假设我在SubmitPerformanceController中有一个名为“Test”的函数，然后我可以这样做:

public function test() { 
  $prc = new PrintReportController();
  $prc->getPrintReport();
 }

namespace App\Http\Controllers;

//call the controller you want to use its methods
use App\Http\Controllers\AdminController;

use Illuminate\Http\Request;

use App\Http\Requests;

class MealController extends Controller
   {
      public function try_call( AdminController $admin){
         return $admin->index();   
    }
   }

你可以在PrintReportController中使用一个静态方法，然后像这样从SubmitPerformanceController调用它;

namespace App\Http\Controllers;

class PrintReportController extends Controller
{

    public static function getPrintReport()
    {
      return "Printing report";
    }


}



namespace App\Http\Controllers;

use App\Http\Controllers\PrintReportController;

class SubmitPerformanceController extends Controller
{


    public function index()
    {

     echo PrintReportController::getPrintReport();

    }

}

你可以通过实例化它并调用doAction来访问控制器:(put use Illuminate\Support\Facades\App;在控制器类声明之前)

$controller = App::make('\App\Http\Controllers\YouControllerName');
$data = $controller->callAction('controller_method', $parameters);

还要注意，这样做将不会执行该控制器上声明的任何中间件。

在我看来最优雅的方法是:

app(YourController::class)->yourControllerMethod()

这种方法也适用于相同层次的Controller文件:

$printReport = new PrintReportController;

$prinReport->getPrintReport();
