If you really want to use json encoded data in a view, use json_decode()in foreach:
如果您真的想在视图中使用 json 编码数据，请在json_decode()中使用foreach：
@foreach(json_decode($mydata, true) as $value)
Member ID: {{ $value['all_pelanggan']['name'] }}
@endforeach

You didn't followed the question you provided. As stated there you should decode your json in the controller:
您没有按照您提供的问题进行操作。如上所述，您应该在控制器中解码您的 json：
return view('your-view')->with('mydata', json_decode($mydata, true));

First, you have an JSON array. But you are trying to fetch JSON object.
If you are sure there is only one object, then use in your controller Model::<selection-criteria>->first();so that it will return a JSON object. then "your foreach" will come to work.
首先，您有一个 JSON 数组。但是您正在尝试获取 JSON 对象。如果您确定只有一个对象，则在您的控制器中使用，Model::<selection-criteria>->first();以便它返回一个 JSON 对象。然后“你的foreach”将开始工作。
If you are not sure there is only one object or in future it will have more objects, then leave your selection statement as it is(It has ->get()at the end). So it will return an array.
如果您不确定只有一个对象，或者将来会有更多对象，那么请保留您的选择语句（它->get()在最后）。所以它会返回一个数组。
Now modify your foreach to fetch that array. That is your data set is an array and each element is JSON object with sub objects.
现在修改您的 foreach 以获取该数组。也就是说，您的数据集是一个数组，每个元素都是带有子对象的 JSON 对象。
@foreach($mydata as $myDatum)
@foreach($myDatum as $val)
Object label: {{ $val['label'] }}
Member Name: {{ $val['value']->name }}
Member Address: {{ $val['value']->address }}
@endforeach
@endforeach

Can you please try the following
你能试试下面的吗
@for ($i = 0; $i < count($myData); $i++)
Member ID: {{ $myData[i]['value'] }}
@endfor
I hope that works.
我希望这有效。
