我已经能够通过在刀片文件中循环来获取第一步数组，但是，我在提取上面的嵌套“资本” 数组时遇到了一点挑战。我的刀片文件代码如下...

@foreach ($countriesData as $country)

                <div class="p-2">
                    <div class="flex items-center">
                        <div class="ml-4 text-lg leading-7 font-semibold"><p>Country: <strong>{{ $country['name'] }}</strong></p></div>
                    </div>

                    <div class="ml-12">
                        <div class="mt-2 dark:text-gray-400 text-sm">
                            <p>Full name: <strong>{{$country['state_name']}}</strong></p>
                            <p>Continent: <strong>{{$country['un_geoscheme']['region']}}</strong></p>
                            @foreach ($country as $countryCapital)

                                   {{-- <p>Capital: <strong>{{$countryCapital['capital']['name']}}</strong></p>


                            @endforeach
   {{--  Do I foreach again as I have done above, use a for loop or what must I do in this particular scenario? Thanks --}}
                        </div>
                    </div>
                </div>

@endforeach

到目前为止，我遇到了诸如“未定义的数组键”、“无法在字符串上调用字符串”等错误。如果有人能帮我解决这个问题，我会非常高兴。此外，我已经完成了必要的谷歌搜索，但一切都无济于事。谢谢。

像这样尝试 $countryCapital['name']

$country['capital']是数组，像这样迭代：

@foreach ($country['capital'] as $countryCapital)
    <p>Capital: <strong>{{$countryCapital['name']}}</strong></p>
@endforeach
