将多个数组放入一个大型关联数组中

问题描述

我正在使用以下循环创建一组数组:

I am creating a set of arrays with the following loop:

$assessmentArr = explode("&", $assessmentData);

foreach($assessmentArr as $data) {
    $fullArr = explode("_", $data);

    // Break down to only archetype and value
    $resultArr = explode("=", $fullArr[2]);

    //print_r($resultArr);
}

产生以下结果:

Array
(
    [0] => community-support
    [1] => 24
)
Array
(
    [0] => money-rewards
    [1] => 30
)
Array
(
    [0] => status-stability
    [1] => 15
)
Array
(
    [0] => personal-professional-development
    [1] => 32
)
Array
(
    [0] => community-support
    [1] => 9
)
Array
(
    [0] => money-rewards
    [1] => 12
)
Array
(
    [0] => status-stability
    [1] => 16
)
Array
(
    [0] => personal-professional-development
    [1] => 29
)

我需要将这些组合成一个数组，并且在 [0] 值匹配的地方，我需要将 [1] 值添加在一起.

I need to combine these into one array, and where the [0] value matches, I need to add the [1] value together.

所以我希望最终输出类似于:

So I would like the final output to be something like:

Array
(
    [community-support] => 33
    [money-rewards] => 42
    [status-stability] => 31
    [personal-professional-development] => 61
)

我发现了这个问题:如何合并两个通过对合并的值求和来创建数组，这将帮助我合并和添加这些值，但是当数组未分配给变量时，我不确定如何处理.我正在尝试做的事情是可能的还是我的做法错误?

I found this question: How to merge two arrays by summing the merged values which will assist me in merging and adding the values together, but I'm not sure how to go about it when the arrays aren't assigned to a variable. Is what I am trying to do possible or am I going about this the wrong way?

推荐答案

不要让它复杂化，只需检查结果数组是否已经有一个具有该键的元素，如果没有初始化它，否则添加它.例如

Don't make it complicated, just check if the results array already has an element with that key and if not initialize it otherwise add it. E.g.

(在循环中添加此代码):

(Add this code in your loop):

if(!isset($result[$resultArr[0]]))
    $result[$resultArr[0]] = $resultArr[1];
else
    $result[$resultArr[0]] += $resultArr[1];

然后你就有了你想要的数组:

Then you have your desired array:

print_r($result);
