在保持结构的同时求和多维数组中特定键的值
我有一个多维数组，我试图在保持数组结构的同时对值求和。
该数组包含带有特定类型财务数据的data ['tags']的“财务”数组。每个“财务”的键在整个数组中都是相同的，例如，每个“财务”将具有“收入”和“费用”。
公司在整个数组中也是相同的，但需要在最终数组中返回
这是我正在使用的数据数组的确切格式：
$array =
[
[
"financials" => [
[
"data" => [
"tag" => "revenue",
],
"value" => 1,
],
[
"data" => [
"tag" => "expenses",
],
"value" => 10,
],
],
"company" => [
"id" => 1,
"name" => "company, inc",
],
],
[
"financials" => [
[
"data" => [
"tag" => "revenue",
],
"value" => 2,
],
[
"data" => [
"tag" => "expenses",
],
"value" => 20,
],
],
"company" => [
"id" => 1,
"name" => "company, inc",
],
],
];
我试图弄清楚如何对每个data ['tag']值的每个“值”求和，例如，如果计算上述数组，我想要得到的最终结果是：
[
"financials" => [
[
"data" => [
"tag" => "revenue",
],
"value" => 3,
],
[
"data" => [
"tag" => "expenses",
],
"value" => 30,
],
],
"company" => [
"id" => 1,
"name" => "company, inc",
],
],
它保留了原始的数组结构，但已为每个data ['tag']值汇总了财务值。

此代码应执行以下操作：$array = [ [ "financials" => [ [ "data" => [ "tag" => "revenue", ], "value" => 1, ], [ "data" => [ "tag" => "expenses", ], "value" => 10, ], ], "company" => [ "id" => 1, "name" => "company, inc", ], ], [ "company" => [ "id" => 1, "name" => "company, inc", ], "financials" => [ [ "data" => [ "tag" => "revenue", ], "value" => 2, ], [ "data" => [ "tag" => "expenses", ], "value" => 20, ], ], ],];$company = $array[0]['company'];$summedArray = $usedTags = [];$summedArray['company'] = $company;$summedArray['financials'] = [];foreach ($array as $set) { $data = $set['financials']; foreach ($data as $dataSet) { if (in_array($dataSet['data']['tag'], $usedTags) === false) { $summedArray['financials'][] = [ "data" => [ "tag" => $dataSet['data']['tag'] ], "value" => $dataSet['value'] ]; $usedTags[] = $dataSet['data']['tag']; } else { $summedArray['financials'][array_search($dataSet['data']['tag'], $usedTags)]['value'] += $dataSet['value']; } }}var_dump($summedArray);希望对您有帮助
