    public static function callFunction($functionName, $parameters = [])
    {
        if (method_exists(Facade::getFacadeRoot(), $functionName)) {

        } else {
            throw new \Exception("Function {$functionName} does not exist.");
        }
    }
}

use Illuminate\Http\Request;

class UserController extends Controller
{
    public function getUserById($id)
    {
        // 获取用户逻辑
        return response()->json(['user' => 'User with ID ' . $id]);
    }
}

use App\Helpers\DynamicCaller;

$result = DynamicCaller::callFunction('getUserById', [1]);
