Laravel Collections 除了不能按预期工作

Question

我为特定用户的所有地址列表创建了一个集合，并将其称为:

$addresses = collect($user->GetAddress);
$addresses = $addresses->where('deleted', 0);
$addresses = $addresses->except(['deleted', 'created_at', 'updated_at']);

我得到如下输出:

[
        {
            "id": 1,
            "user_id": 1,
            "name": "mr.test",
            "line1": "test1",
            "line2": "test2",
            "pincode": 100,
            "city": "test3",
            "state": "test4",
            "mobile": "test5",
            "default": 0,
            "deleted": 0,
            "created_at": "2017-02-23 09:20:09",
            "updated_at": "2017-02-23 09:20:09"
        }
]

它仍然返回我执行的字段除外。我究竟做错了什么？

我什至尝试过这些:

$addresses = $addresses->each(function ($item, $key) {
    return $item->except(['deleted', 'created_at', 'updated_at']);
});

和

$addresses = $addresses->each->except(['deleted', 'created_at', 'updated_at']);

except仅当您有一个带键的数组时才有效，不适用于嵌套数组。您对每个函数的解决方案应该有效，但我认为您必须转换 $item先收藏。

像这样:

$addresses = $addresses->map(function ($item, $key) {
    return collect($item)->except(['deleted', 'created_at', 'updated_at'])->toArray();
});
