我试图在我看来循环遍历一个多维数组。
数组(我将$ mailchimp从我的控制器传递给我的视图)是:
array:19 [▼
"id" => "f3200e9cc5a900bb7c075103b871232f0"
"email_address" => "john.doe@discworld.com"
"unique_email_id" => "xalasd"
"email_type" => "html"
"status" => "subscribed"
"merge_fields" => array:2 [▼
"FNAME" => "John"
"LNAME" => "Doe"
]
"stats" => array:2 [▶]
"ip_signup" => ""
"timestamp_signup" => ""
"ip_opt" => "93.212.91.32"
"timestamp_opt" => "2016-10-27T13:53:02+00:00"
"member_rating" => 2
"last_changed" => "2016-10-27T13:53:02+00:00"
"language" => ""
"vip" => false
"email_client" => ""
"location" => array:6 [▶]
"list_id" => "76980934492"
"_links" => array:8 [▶]
]
在我看来使用此代码:
@foreach($mailchimp as $user)
@foreach($user as $key => $value)
<ul>
<li>{{$value}}</li>
</ul>
@endforeach
@endforeach
抛出异常:为foreach()提供的参数无效
有人可以告诉我如何解决这个问题吗?

你期望每个第一个数组的值也是一个数组。情况并非如此,只有第一个数组中的某些值是数组,因此必须设置条件。您可以使用is_array
帮助程序查看第一个数组中的值是否为实际数组,如果是,则循环遍历每个数组。
foreach($a as $b){
if(is_array($b)){
foreach($b as $c){
echo($c);
}
}
}

正如卡洛斯所提到的,您遇到的主要问题是因为您试图回应数组find his answer here。
关于您的第二个问题Thanks Carlos. It tried you solution with this result: htmlentities() expects parameter 1 to be string, array given
您是否在该页面上有任何其他代码,可能是{{Form :: text(&#39; something&#39;,$ array)}}
