Question

我将变量$mailchimp从我的Controller传递给我的视图。

这是我用{{dd($mailchimp)}}

得到的

    array:8 [▼
      "id" => "xyz123"
      "email_address" => "john.doe@discworld.com"
      "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"
    ]

我如何循环遍历此数组（$ mailchimp）？使用下面的代码我得到一个例外：“htmlentities（）期望参数1是字符串，给定数组”

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

更新：在我的控制器中使用此代码

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的建议不再适用。

此stil不起作用：

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

Answer 1

您不需要迭代int(a.size())-int(b.size())-1。如果$user是一组用户，请执行以下操作：

$mailchimp

Answer 2

由于您只对打印数组中的值感兴趣，因此可以使用array_flatten删除嵌套数组，然后遍历结果：

@foreach(array_flatten($mailchimp) as $userData)    
    {{$userData}} 
@endforeach
