Question

我需要访问每个级别。我正在使用laravel blade和php。我一直在尝试一些不同的方法但没有成功，这是我尝试过的一个例子：

@foreach($exercisePlan as $al)
   @if(isset($al->exercises))
     <li>{{$al->exercise->description}}</li>
   @endif
@endforeach

这是我的Json，如果有人能帮助我，我将非常感激。提前谢谢！

知道了：

                @foreach($exercisePlan as $plan)
                    @foreach($plan->exercises as $exercises)
                        @foreach($exercises->exercise as $exercise)
                            {{$exercise->name}}
                        @endforeach
                    @endforeach
                @endforeach
