Question

我想以排序格式获取数据。这是我的数组

Illuminate\Support\Collection Object
(
    [items:protected] => Array
    (
        [0] => stdClass Object
            (
                [id] => 47
                [user_id] => 2
                [title] => SSS
                [category_id] => 4
                [description] => sss description sss description sss description sss description sss description sss description sss description sss description sss description sss description
                [deliverable_status] => pending reviews
                [created_at] => 2018-01-17 13:26:19
                [updated_at] => 2018-01-17 13:26:19
                [category_name] => Designs
                [reviewer_user_id] => 3
                [email] => def@yopmail.com
            )

        [1] => stdClass Object
            (
                [id] => 47
                [user_id] => 2
                [title] => SSS
                [category_id] => 4
                [description] => sss description sss description sss description sss description sss description sss description sss description sss description sss description sss description
                [deliverable_status] => pending reviews
                [created_at] => 2018-01-17 13:26:19
                [updated_at] => 2018-01-17 13:26:19
                [category_name] => Designs
                [reviewer_user_id] => 4
                [email] => abc@yopmail.com
            )

    )

）

这两条记录除了评论者ID和电子邮件之外都有相同的数据。所以我需要单个数组和两个电子邮件。我需要单个数组中的那些。这是我需要的样本数组

        [0] => stdClass Object
            (
                [id] => 47
                [user_id] => 2
                [title] => SSS
                [category_id] => 4
                [description] => sss description sss description sss description sss description sss description sss description sss description sss description sss description sss description
                [deliverable_status] => pending reviews
                [created_at] => 2018-01-17 13:26:19
                [updated_at] => 2018-01-17 13:26:19
                [category_name] => Designs
                [email] => [0] => stdClass Object (
                                       [0] => 'def@yopmail.com',
                                       [1] => 'abc@yopmail.com',
                                  )             
           )

Answer 1

使用以下代码：

$result = $collection->unique('id')
    ->map(function ($item) use ($collection) {
        $item->email = $collection->where('id', $item->id)
            ->pluck('email')
            ->toArray();
        return $item;
    })
    ->first();

结果将是：

stdClass Object
            (
                [id] => 47
                [user_id] => 2
                [title] => SSS
                [category_id] => 4
                [description] => sss description sss description sss description sss description sss description sss description sss description sss description sss description sss description
                [deliverable_status] => pending reviews
                [created_at] => 2018-01-17 13:26:19
                [updated_at] => 2018-01-17 13:26:19
                [category_name] => Designs
                [email] => Array (
                                       [0] => 'def@yopmail.com',
                                       [1] => 'abc@yopmail.com',
                                  )             
           )

Answer 2

您可以尝试：

$sortedarray = array_unique(array_merge($items[0],$items[1]), SORT_REGULAR);
