        }

    }
}

这里是控制器摘录

$properties = json_decode($file, true);
return view('properties.all-properties')->with('properties',$properties);

这是我认为的测试

@foreach($properties as $details) 
    {{ $details["streetNumber"] }}
@endforeach

我想循环遍历数据并构建列表信息

【问题讨论】：

查看streetNumber 在您的阵列中的位置。它不在顶层。
当你的数组被这样格式化时，很难看到它的样子。
在这个示例中，我只在 ["privateRemarks"] 之后显示了一个列表 ["property"]，json 显示了 26 个列表，你们可以显示一些示例代码或指出一个好的关于循环 JSON 数组的教程？

【解决方案1】：

streetNumber 在address 内。所以理想情况下应该是

@foreach($properties as $details) 
    {{ $details["address"]["streetNumber"] }}
@endforeach

将来，如果您遇到此类问题，您的第一步是打印$details 并查看其中的内容。
