我已将 Facebook 用户朋友的 FBID 存储在 mysql 数据库中的字符串中。字符串如下所示：

"fbid1,fbid2,fbid3...etc..."

我正在尝试在视图中使用特定的 FBID（例如，呼叫配置文件图像）。我的问题是，如何在 Laravel 4 视图中执行此操作？我正在尝试以下操作：

array = explode(",", {{ Auth::user()->friend_ids_unpacked}});

但是，这只是将字符串与其他部分作为文本打印出来。我知道这是不正确的，但我不知道如何在 Laravel 的视图中执行 php 调用。

谢谢您的帮助。

您正在尝试做两件不同的事情。假设您想结交一群朋友-您可以这样做：

<? $array = explode(",", Auth::user()->friend_ids_unpacked); ?>

然后，您可以像这样使用数组：

@foreach ($array as $x)
    <p>This is another id: {{ $x }}</p>
@endforeach

移动花括号以完全包含 PHP 调用：

{{ $array = explode(",", Auth::user()->friend_ids_unpacked); }}
