php - PHP 数组合并和删除重复问题

Question

我有两个数组，由结果填充。

1) users_facebook & 2) users_twitter

Array
(
    [users_facebook] => Array
    (
        [0] => Array
            (
                [id] => "180",
                [email] => "",
                [first_name] => "Djon",
                [last_name] => "Katview"
        ),
        [1] => Array
            (
                [id] => "182",
                [email] => "",
                [first_name] => "Awaaru",
                [last_name] => "Bhejafry"
        )
    ),

    [users_twitter] => Array
    (
        [0] => Array
            (
                [id] => "180",
                [email] => "",
                [first_name] => "Djon",
                [last_name] => "Katview"
        ),
        [1] => Array
            (
                [id] => "181",
                [email] => "",
                [first_name] => "Kavritis",
                [last_name] => "Abrfafda"
        ),
        [2] => Array
            (
                [id] => "182",
                [email] => "",
                [first_name] => "Awaaru",
                [last_name] => "Bhejafry"
        )
    ),
)

我想选择两个数组中具有相同“id”的元素并将其附加到新数组，例如“user_final_array”

当它附加到新数组时，我想从两个数组中删除它。

p.s.:不匹配的元素必须保持原样。我已经搞乱了它近 3 小时

添加:

结果数组将类似于:

Array
(
    [users_facebook] => Array
    (
    ),

    [users_twitter] => Array
    (
        [0] => Array
            (
                [id] => "181",
                [email] => "",
                [first_name] => "Kavritis",
                [last_name] => "Abrfafda"
            )
    ),

    [users_final_array] => Array
    (
        [0] => Array
            (
                [id] => "180",
                [email] => "",
                [first_name] => "Djon",
                [last_name] => "Katview"
        ),
        [1] => Array
            (
                [id] => "182",
                [email] => "",
                [first_name] => "Awaaru",
                [last_name] => "Bhejafry"
        )
    ),
)

通过解码将其转换为 json 到数组。然后尝试将这两个数组合并为一个数组。合并后使用 array_unique() 函数删除重复项，如下

array_unique($merge_array);
