Question

现在的数组如下Array
(
    [0] => Array
        (
            [ip] => 192.168.1.1
            [timestamp] => 1482719333
            [ports] => Array
                (
                    [0] => Array
                        (
                            [port] => 1122
                            [status] => open
                            [ttl] => 63
                        )
                )
        )
                
        [1] => Array
        (
            [ip] => 192.168.1.2

                        )
                )
        )
            [2] => Array
        (
            [ip] => 192.168.1.1
            [timestamp] => 1482719333
            [ports] => Array
                (

                                    [title] => awdawdawd
                                )
                        )
                )
        )
        [3] => Array
        (

                            [status] => open
                            [ttl] => 63
                        )
                )
        )
)想合并成下面这样的结果
Array

Answer 3

构造一个hashmap，把要去重的字段作为hashmap的key，都放进hashmap自然去重复
