数组中 Facebook 数据的 foreach 循环 - foreach loop for Facebook data in array

我正在做一个facebook图形api调用并取回数据。但由于某种原因无法循环它。是因为受到保护吗？或者我的 foreach 循环是错误的。

这是我在视图中var_export（$user_pages）时的数据

var_export（$user页）

这是我的循环，它抛出一个错误，说"为 foreach（）提供的参数无效（查看：/Library/WebServer/Documents/fbLogin/app/views/hello.blade.php）'"

@foreach($user_pages as $pages)
                {{ $pages->name }}
                {{ $pages->category }}
@endforeach

我也尝试过var_dump（$user_pages->backingData），它显示错误说"无法访问受保护的属性Facebook''GraphObject：：$backingData"

数据是否不可访问？

已发布结果 var_export**好的，我在调用图形api时使用了facebook asArray（）方法，现在数据更具可读性。只需要循环通过它。* 在 asArray（）之后使用新var_dump更新了帖子

将我的 api 请求更改为

return $response->getGraphObject()->getProperty('data')->asArray();

从

return $response->getGraphObject();

现在以简单的数组形式获取数据，通过它我可以轻松地使用 foreach 进行循环

@foreach($user_pages as $user_pages)
                {{ $user_pages->name }}
                {{ $user_pages->category }}
@endforeach
