php - Laravel 5 循环遍历数组

Question

我正在将变量 $mailchimp 从我的 Controller 传递到我的 View 。

这是我用 {{dd($mailchimp)}}

得到的

    array:8 [▼
      "id" => "xyz123"
      "email_address" => "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="88e2e7e0e6a6ece7edc8ece1fbebffe7fae4eca6ebe7e5" rel="noreferrer noopener nofollow">[email protected]</a>"
      "unique_email_id" => "c9a36649c8"
      "email_type" => "html"
      "status" => "subscribed"
      "merge_fields" => array:2 [▼
        "FNAME" => "John"
        "LNAME" => "Doe"
      ]
      "stats" => array:2 [▼
        "avg_open_rate" => 0
        "avg_click_rate" => 0
      ]
      "list_id" => "769808qeqw92"
    ]

我如何循环遍历这个数组($mailchimp)？使用下面的代码我得到一个异常:“htmlentities() 期望参数 1 为字符串，给定数组”

@foreach($mailchimp as $user)
  @if(is_array($user))
    @foreach($user as $key => $value)
      {{$value}}
    @endforeach
  @endif
@endforeach

更新: 在我的 Controller 中使用此代码

public function index()
{   //Fetch all subscribers from DB
    $subscribers = Subscriber::where('user_id', Auth::user()->id)->orderBy('created_at','asc')->get();

    foreach ($subscribers as $key => $subscriber) {
      //Check if the local subscriber is also present in mailchimp
      $mailchimp = Newsletter::getMember($subscriber->email);
    }

    return view('backend.newsletter.contacts.index')->withSubscribers($subscribers)
                                                    ->withMailchimp($mailchimp);
}

我需要迭代 mailchimp 数组。由于有多个用户，alexey 的建议不再有效。

这个样式不起作用:

@foreach($mailchimp as $key => $user)
    {{$user}}
  @endforeach

您不需要迭代$user。如果 $mailchimp 是用户数组，请执行以下操作:

  {{ $mailchimp['email_adress'] }}
  {{ $mailchimp['merge_fields']['FNAME'] }} {{ $mailchimp['merge_fields']['LNAME'] }}
