使用 Laravel PHP 提取单行值一切正常，但我找不到提取 N 级值的方法，例如 [Packages] 中显示的值

Answer 1

控制器$packages = [];foreach($response['Data']['Packages'] as $p => $package) {&nbsp; &nbsp; foreach($package['Activity'] as $a => $activity) {&nbsp; &nbsp; &nbsp; &nbsp; $packages[$p]['Activity'][] = [&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'Description' => $activity['Description'],&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'City' => $activity['Location']['City'],&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'State' => $activity['Location']['State'],&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'Country' => $activity['Location']['Country'],&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'Time' => $activity['Time'],&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'StatusCode' => $activity['StatusCode'],&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'StatusTypeCode' => $activity['StatusTypeCode'],&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'StatusDescription' => $activity['StatusDescription'],&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'Signatory' => $activity['Signatory'],&nbsp; &nbsp; &nbsp; &nbsp; ];&nbsp; &nbsp; }}return view('ship2b/trackresults', compact('packages'));看法@foreach ($packages as $package)&nbsp; &nbsp; @foreach ($package['Activity'] as $event)&nbsp; &nbsp; &nbsp; &nbsp; <div>{{ $event['Description'] }}</div>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; <div>{{ $event['City'] }}</div>&nbsp; &nbsp; &nbsp; &nbsp; <div>{{ $event['State'] }}</div>&nbsp; &nbsp; &nbsp; &nbsp; <div>{{ $event['Country'] }}</div>&nbsp; &nbsp; &nbsp; &nbsp; <div>{{ $event['Time'] }}</div>&nbsp; &nbsp; &nbsp; &nbsp; <div>{{ $event['StatusCode'] }}</div>&nbsp; &nbsp; &nbsp; &nbsp; <div>{{ $event['StatusTypeCode'] }}</div>&nbsp; &nbsp; &nbsp; &nbsp; <div>{{ $event['StatusDescription'] }}</div>&nbsp; &nbsp; &nbsp; &nbsp; <div>{{ $event['Signatory'] }}</div>&nbsp; &nbsp; @endforeach@endforeach
