php将子数组推送到父数组中

我正在获取数据，并试图将

子项

数据推送到其父数组中，但没有在数组中获得正确的索引

Array
(
    [0] => stdClass Object
        (
            [id] => 708
            [user_id] => 104
            [component] => activity

                        (
                            [id] => 710
                            [user_id] => 104
                            [component] => activity

                                )

                            [depth] => 2
                        )

                )

            [depth] => 1
        )

    [1] => stdClass Object
        (
            [id] => 709
            [user_id] => 104
            [component] => activity
            [type] => activity_comment
            [action] => XXXX XXXX posted a new activity comment
            [content] => hello manan 2
            [primary_link] => 
            [item_id] => 707
            [secondary_item_id] => 707
            [date_recorded] => 2018-02-19 05:01:38
            [hide_sitewide] => 0
            [mptt_left] => 6
            [mptt_right] => 7
            [is_spam] => 0
            [user_email] => xxxxxxx@xxxxx.xxx
            [user_nicename] => manan88

            [display_name] => XXXX XXXX
            [user_fullname] => XXXX XXXX
            [children] => Array
                (
                )

            [depth] => 1
        )

)

但我想将所有子值合并回父数组，如下所示：

Array

    [0] => stdClass Object
        (
            [id] => 708
            [user_id] => 104
            [component] => activity
            [type] => activity_comment
            [action] => XXXX XXXX posted a new activity comment
            [content] => hello manan
            [primary_link] => 
            [item_id] => 707
            [secondary_item_id] => 707
            [date_recorded] => 2018-02-19 05:01:16
            [hide_sitewide] => 0

我尝试过使用

array\u push

，之后，我使用的

array\u multisort

不起作用。你知道吗

for ($i=0; $i<count($data); $i++) {
    // Move children to main array
    $children = $data[$i]->children;
    if (!empty($children)) {
        foreach ($children as $key => $value) {
            array_push($data, $children[$key]);
        }
    }
}

if (!empty($data)) {
    array_multisort($data, SORT_ASC);
}

$i=0；$ichildren； 如果（！空（$children））{ foreach（$key=>$value的子项）{ 数组_push（$data，$children[$key]）； } } } 如果（！空（$data））{ 数组\多排序（$data，排序\ ASC）； }

您希望从问题中获取所有子级别2数组。 并使用

array\u merge\u recursive（）

合并数组

$newarray = array_merge_recursive($oldarray,$newarray);

请参阅文档

您可以尝试此代码

for ($i=0; $i<count($data); $i++) {
    // Move children to main array
    $children = $data[$i]->children;
    if (!empty($children)) {
      array_push($data, $children);
    }
}

if (!empty($data)) {
    array_multisort($data, SORT_ASC);
}

$i=0；$ichildren； 如果（！空（$children））{ 数组推送（$data，$children）； } } 如果（！空（$data））{ 数组\多排序（$data，排序\ ASC）； }
