如何在 PHP 中獲取多維關聯數組到子多維關聯數組？

Question

我有一個多維 PHP 數組，我怎樣才能得到一個多維關聯數組，其中鍵是meetingId['0']的值，值是playback['0']的值？

Array(
    [returncode] => Array([0] => SUCCESS)
    [message] => Array()
    [0] => Array(
        [meetingId] => Array([0] =>3049)
        [name] => Array([0] => Measurement)
        [playback] => Array([0] => mid2020)
    )
    [1] => Array(
        [meetingId] => Array([0] => 3048)
        [name] => Array([0] => Measurement)
        [playback] => Array([0] => mid2019)
    )
    [2] => Array(
        [meetingId] => Array([0] => 3047)
        [name] => Array([0] => Measurement)
        [playback] => Array([0] => mid2018)
    )
)

結果將是：

array('3049'=>'mid2020','3048'=>'mid2019','3047'=>'mid2018')

我找到了解決這個問題的方法，

$result = array_combine(array_column(array_column($room_recordings,"meetingId"),0), array_column(array_column($room_recordings,"playback"),0));
