如何总结相同的密钥的阵列的价值观？ [英] How to sum values of the array of the same key?

问题描述

我如何添加键值的所有值的 [gozhi] 的？需要注意的是 [gozhi] 的关键是的动态的。

的输入数组：的

阵列
（
    [0] =＆GT;排列
        （
            [gozhi] =＆GT; 2
            [uzorong] =＆GT; 1
            [ngangla] =＆GT; 4
            [langthel] =＆GT;五
        ）    [1] =＆GT;排列
        （
            [gozhi] =＆GT;五
            [uzorong] =＆GT; 0
            [ngangla] =＆GT; 3
            [langthel] =＆GT; 2
        ）    [2] =＆GT;排列
        （
            [gozhi] =＆GT; 3
            [uzorong] =＆GT; 0
            [ngangla] =＆GT; 1
            [langthel] =＆GT; 3
        ）
）


的期望的结果：的

阵列
（
    [gozhi] =＆GT; 10
    [uzorong] =＆GT; 1
    [ngangla] =＆GT; 8
    [langthel] =＆GT; 10
）


解决方案

  $ sumArray =阵列（）;的foreach（$ myArray的为$ K =＆GT; $子阵列）{
  的foreach（$子阵为的$ id =＆GT; $值）{
    $ sumArray [$ ID] + = $价值;
  }
}的print_r（$ sumArray）;
 

How can I add all the values of the key [gozhi]? Note that [gozhi] key is dynamic.

Input array :

Array
(
    [0] => Array
        (
            [gozhi] => 2
            [uzorong] => 1
            [ngangla] => 4
            [langthel] => 5
        )

    [1] => Array
        (
            [gozhi] => 5
            [uzorong] => 0
            [ngangla] => 3
            [langthel] => 2
        )

    [2] => Array
        (
            [gozhi] => 3
            [uzorong] => 0
            [ngangla] => 1
            [langthel] => 3
        )
)

Desired result :

Array
(
    [gozhi] => 10
    [uzorong] => 1
    [ngangla] => 8
    [langthel] => 10
)

解决方案

$sumArray = array();

foreach ($myArray as $k=>$subArray) {
  foreach ($subArray as $id=>$value) {
    $sumArray[$id]+=$value;
  }
}

print_r($sumArray);
