如何访问 laravel 刀片文件中的嵌套数组数据？

我的数组：

            "on_hand": "0"
          }
        }
      }
    }

我将此数组作为 items 传递给我的 laravel Blade 文件并访问相关数据。但是我很难访问 color_size_grid 数组中的数据。如何在 foreach 循环中打印所有 size_description？提前致谢。

在我的刀片文件中做了什么：

@foreach ($items as $item)
        <div class="print-block" style="page-break-inside: avoid;">
            <div class="print-block__img">
                <img src="" alt="">
            </div>
            <div class="print-block__details">
                <h3>{{$item['item_description']}}</h3>
                <div class="code">{{$item['amt_item']}}</div>
                <div class="price">
                    <strong>W:</strong> USD {{$item['wholesale_price']}} | <strong>R:</strong> USD {{$item['retail_price']}}
                </div>
                <table class="other-info">
                    <tr>
                        <td>
                            <strong>Sizes: </strong>
                        </td>
                        <td></td>
                    </tr>
                    <tr>
                        <td>
                            <strong>Colors: </strong>
                        </td>
                        <td></td>
                    </tr>
                </table>
            </div>
        </div>
    @endforeach

对于 Sizes，现在我想打印 color_size_grid 数组中的所有 size_descriptions。

每种颜色的可用尺寸如下：

Sizes:
CORA - X SMALL, MEDIUM, X LARGE, LARGE, SMALL
CHA - ...........

感谢您的回答。但我在这里得到一个错误，“试图获取非对象的属性'color_size_grid'
作为 laravel 的新手，能否给我举个例子
我在答案里改了
是的，现在可以使用了，非常感谢 :)，我可以修改它以显示每种颜色的尺寸吗？
太好了，是的，你可以修改任何你想要的 ;-)
