PHP：重新格式化数组

Question

帮我重新格式化我的数组：

Array
(
    [sampleArr] => Array
        (
            [0] => Array
                (
                    [id] => 1
                )

            [1] => Array
                (
                    [id] => 2
                )

        )

)

这是我的数组需要重新格式化，如上面的数组：

Array
(
    [sampleArr] => Array
        (
            [id] => 1
            [id2] => 2
        )

)

可能是你可以像这样重新循环你的数组。

$data['sampleArr'] = [];
foreach($data['sampleArr'] as $key => $value) {
   $k = !empty($key) ? $key : "";
   $format['sampleArr'][$value['id'].$k] = $value['id'];
}
