在php中删除多维数组中的重复值

function removeDuplicates($array) {
    return array_map(function($subArray) {
        return array_values(array_unique($subArray));
    }, $array);
}

// 示例用法
$multiArray = [
    [1, 2, 3, 2],
    [4, 5, 6, 4],
    [7, 8, 9, 8]
];

$result = removeDuplicates($multiArray);
print_r($result);

Array
(
    [0] => Array
        (
            [0] => 1
            [1] => 2
            [2] => 3
        )

    [1] => Array
        (
            [0] => 4
            [1] => 5
            [2] => 6
        )

    [2] => Array
        (
            [0] => 7
            [1] => 8
            [2] => 9
        )
