我如何合并这个数组或删除一个键

Question

下面是我到目前为止编译的数组的一个示例。我是从一个facebook图形api调用生成数组，并希望删除数组包装每个对象，所以我只是有一个列表下的数据数组。最好我需要一个动态的解决方案，因为他们可能不止一个[0]=> Array， [1] => Array等....

stdClass Object
(
    [data] => Array
        (
            [0] => Array
                (
                    [0] => stdClass Object
                        (
                            [id] => 21744379694_10154626935079695
                            [created_time] => 2016-10-16T06:29:28+0000
                            [from] => stdClass Object
                                (
                                    [name] => Tony Hawk
                                    [id] => 21744379694
                                )
                        )
                )
            [1] => Array
                (
                    [0] => stdClass Object
                        (
                            [id] => 50043151918_10154176205946919
                            [created_time] => 2016-10-15T20:04:22+0000
                            [from] => stdClass Object
                                (
                                    [name] => GoPro
                                    [id] => 50043151918
                                )
                        )
                )
        )
)

我希望数组最终看起来像这样。这里最好的方法是什么?

stdClass Object
(
    [data] => Array
        (
            [0] => stdClass Object
                (
                    [id] => 21744379694_10154626935079695
                    [created_time] => 2016-10-16T06:29:28+0000
                    [from] => stdClass Object
                        (
                            [name] => Tony Hawk
                            [id] => 21744379694
                        )
                )
            [1] => stdClass Object
                (
                    [id] => 50043151918_10154176205946919
                    [created_time] => 2016-10-15T20:04:22+0000
                    [from] => stdClass Object
                        (
                            [name] => GoPro
                            [id] => 50043151918
                        )
                )
        )
)

Answer 1

假设您的数据存储在变量$data中，您可以这样做:

foreach($data->data as &$el) {
    $el = $el[0];
}

现在包装数组已经被移除。

Answer 2

你可以这样做:

if ($data && $data->data){ $new = array_values($data->data); }
