您可以这样做：

$result = [];
$cb = function ($arr) use (&$result) {
    in_array($arr, $result) || $result[] = $arr;
    return false;
};

array_map($cb, array_merge($a, $b));
print_r($result);

希望有所帮助

UPD例如源数据：

$a = [
    [
        'id' => '7838585925 ',
        'title' => '1778-1978 CAPTAIN COOK DISCOVERS HAWAII - EXCLUSIVE ALBUM, GREAT BUY !! ',
        'sku' => 'A-07582 ',
    ],
    [
        'id' => '7841101829',
        'title' => '1965 International Cooperation Year Crown Agents SET 62V MNH diff. countries',
        'sku' => 'A-02841',
    ],
];

$b = [
    [
        'id' => '7841101829',
        'title' => '1965 International Cooperation Year Crown Agents SET 62V MNH diff. countries',
        'sku' => 'A-02841',
    ],
    [
        'id' => '7840685253',
        'title' => 'ADEN - 1937 KGVI CORONATION - 3V - FDC REGISTERED',
        'sku' => 'A-03548',
    ],
];

输出：

Array
(
    [0] => Array
        (
            [id] => 7838585925 
            [title] => 1778-1978 CAPTAIN COOK DISCOVERS HAWAII - EXCLUSIVE ALBUM, GREAT BUY !! 
            [sku] => A-07582 
        )

    [1] => Array
        (
            [id] => 7841101829
            [title] => 1965 International Cooperation Year Crown Agents SET 62V MNH diff. countries
            [sku] => A-02841
        )

    [2] => Array
        (
            [id] => 7840685253
            [title] => ADEN - 1937 KGVI CORONATION - 3V - FDC REGISTERED
            [sku] => A-03548
        )

)

从两个不同的数组中删除唯一条目
