How to get multidimensional associative array to sub multidimensional associative array in PHP?

Question

I have a multidimensional PHP array, how can I get a multidimensional associative array where the key will be the value of meetingId['0'] and value will be the value of playback['0']?

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)
    )
)

Result will be:

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

Answer 1

I found the solution to this problem,

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