萨姆其存储为laravel阵列和组由相同的id 4

Question

我曾经在一个称为被存储为一个阵列的“图像”表中的字段，

$new_item_photos = Item::whereIn('id', [10, 15, 10])->get(); 

     foreach ($new_item_photos as $new_photos) { 
      if ($new_photos->id == $new_photos->id) { 
       $total_photos += count($new_photos->images); 
      } else { 
       $total_photos = count($new_photos->images); 
      } 

      echo $total_photos."<br>"; 
     } 

我得到的结果像

id photos 
10 8 
15 9 
10 7 

现在我要总结所有的$ TOTAL_PHOTOS从环，前过滤重复的ID：

id photos 
10 15 
15 9 

能anyo ne请帮助我吗？

PS：将图像保存在阵列格式表

可以使用数组来存储照片计数的每个ID。这是修改的例子，可以帮助你进一步

$new_photos = Item::whereIn('id', [10, 15, 10])->get(); 
$total_photos=[]; 

foreach ($new_photos_dealers as $new_photos_dealer) { 
    if ($new_photos->id == $new_photos->id) { 
    if(array_key_exists($new_photos->id,$total_photos)) { 
      $total_photos[$new_photos->id] += count($new_photos->images); 
    } else { 
      $total_photos[$new_photos->id] = count($new_photos->images); 
    { 
     $total_photos[$new_photos->id] += count($new_photos->images); 
    } else { 
     $total_photos[$new_photos->id] = count($new_photos->images); 
    } 

    echo print_r($total_photos, true)."<br>"; 
}
