如何在多维数组中计数

Question

我在使用多维数组时遇到问题：

 Array
(
    [start] => Array
        (
            [0] => mymail@google.mail
            [1] => antohermail@yahoo.com
            [2] => antohermail@yahoo.com
            [3] => mymail@google.mail
            [4] => 222222@google.mail
            [5] => mymail@google.mail
            [6] => bot001e08@lopbot001
            [7] => antohermail@yahoo.com
            [8] => mymail@google.mail
            [9] => bot001e02@lopbot001.mail
        )

    [name] => Array
        (
            [0] => 43
            [1] => 17
            [2] => 15
            [3] => 34
            [4] => 12
            [5] => 37
            [6] => 14
            [7] => 12
            [8] => 33
            [9] => 25
        )

)

这个多数组有相同数量的键。我想显示所有不同的电子邮件（起始数组）并计算名称数组中的所有值。

所以期望的输出应该是这样的：

我的邮箱@google.mail: 43+34+37+23 = 137

antohermail@yahoo.com: 17 +15+ 12 = 44

222222@google.mail: 12

bot001e08@lopbot001: 14

bot001e02@lopbot001.mail: 25

使用特殊函数我可以得到这样的结果：

Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [mymail@google.mail] => 43
                    [antohermail@yahoo.com] => 17
                    [antohermail@yahoo.com] => 15
                )

            [1] => Array
                (
                    [mymail@google.mail] => 34
                    [222222@google.mail] => 12
                )

            [2] => Array
                (
                    [mymail@google.mail] => 37
                    [bot001e08@lopbot001] => 14
                    [222222@google.mail] => 12
                )

            [3] => Array
                (
                    [mymail@google.mail] => 33
                    [bot001e02@lopbot001.mail] => 25
                )

        )

)

但我仍然无法计算这个多数组的值

Answer 1

使用这个带有嵌套索引的简单循环

$mails = array();
        foreach ($data['start'] as $key => $value) {
            $mails[$value]['sum'] = @$mails[$value]['sum'] + $data['name'][$key];
        }
    
 print_r($mails);

结果：

(
[mymail@google.mail] => Array
    (
        [sum] => 147
    )

[antohermail@yahoo.com] => Array
    (
        [sum] => 44
    )

[222222@google.mail] => Array
    (
        [sum] => 12
    )

[bot001e08@lopbot001] => Array
    (
        [sum] => 14
    )

[bot001e02@lopbot001.mail] => Array
    (
        [sum] => 25
    )

)
