$parameters = [];
$reflector = new ReflectionFunction('myTestFunction');
foreach ($reflector->getParameters() as $key => $parameter) {
    $class = $parameter->getClass();
    if ($class) {
        $parameters[$key] = App::make($class->name);
    } else {
        $parameters[$key] = null;
    }
}
call_user_func_array('myTestFunction', $parameters);

public function call($callback, array $parameters = [], $defaultMethod = null)

App::call('\App\Http\Controllers\Api\myTestFunction');

App::call([$object, 'myTestMethod']);

public function show(Request $request,$id){
$record = $request->find($id);
dd($record);
}

class A{}
class B{
   function abc(A $obj){}
}

-so function abc of class B will accept object of Class A.
like:
$obj = new A();
$obj2 = new B();
$obj2->abc($obj);

class Foo {
   public function bar(Baz $baz)
   {
        $this->custom(...$baz);
   }

   protected function custom(Baz $baz, Baz2 $baz2, Baz3 $baz3)
   {
        return $baz3;
   }
}
