不能在laravel使用类型为stdClass的对象作为数组错误5.4

Question

我使用Laravel 5.4，当我使用的ID与地图功能获取图像，并返回图像目录，我得到这个错误

这里面控制器

功能

$shipping = DB::table('shipping') 
      ->select('shipping.id','products.name','shipping.is_return','shipping.pro_id as pid','shipping.tracking_url') 
      ->join('products','shipping.pro_id','=','products.id') 
      ->orderBy('shipping.id', 'desc') 
      ->limit('5')->get(); 

     $shipping->map(function ($ship) { 
      $directory = 'uploads/products/images/'.$ship->pid; 
      if (is_dir($directory)) { 
      $files = scandir ($directory); 
      $img_file = $directory.'/'.$files[2]; 
      $ship->front_img = $img_file; 
      print_r($ship['front_img']);exit; 
      }   
     }); 

当我尝试打印输出时显示错误。

您尝试使用数组中获取价值，但$ship是反对

$shipping = DB::table('shipping')->select('shipping.id','products.name','shipping.is_return','shipping.pro_id as pid','shipping.tracking_url') 
      ->join('products','shipping.pro_id','=','products.id') 
      ->orderBy('shipping.id', 'desc') 
      ->limit('5')->get(); 

     $shipping->map(function ($ship) { 
      $directory = 'uploads/products/images/'.$ship->pid; 
      if (is_dir($directory)) { 
      $files = scandir ($directory); 
      $img_file = $directory.'/'.$files[2]; 
      $ship->front_img = $img_file; 
      print_r($ship->front_img);exit; //change here 
      }   
     });
