PHP仅从键与其他数组相交的多维数组中获取值

$array = [
    ['a' => 1, 'b' => 2],
    ['a' => 3, 'c' => 4],
    ['b' => 5, 'd' => 6]
];

$array1 = [
    ['a' => 1, 'b' => 2],
    ['a' => 3, 'c' => 4],
    ['b' => 5, 'd' => 6]
];

$array2 = ['a', 'b'];

$array1 = [
    ['a' => 1, 'b' => 2],
    ['a' => 3, 'c' => 4],
    ['b' => 5, 'd' => 6]
];

$array2 = ['a', 'b'];

$result = [];

foreach ($array1 as $subArray) {
    foreach ($subArray as $key => $value) {
        if (in_array($key, $array2)) {
            $result[$key][] = $value;
        }
    }
}

print_r($result);

Array
(
    [a] => Array
        (
            [0] => 1
            [1] => 3
        )

    [b] => Array
        (
            [0] => 2
            [1] => 5
        )
