如何通过其他密钥通过相同的密钥和组求和值

Question

我想用相同的参考号码对产品进行求和，但我有第三个参数，例如维度。 （...，24,26mm，...），并且当它们具有相同的尺寸时，我无法将此值总和为而只有。我试过这个：Group a multidimensional array by a particular value?但是如何总结数值？ 我的数组是这样的：

Array 
(
    [0] => Array 
     (
      [0] => 2 
      [1] => 790180X 
      [2] => 26mm 
     ) 
    [1] => Array 
     (
      [0] => 4 
      [1] => 762182Z 
     ) 
    [2] => Array 
     (
      [0] => 2 
      [1] => 072182X 
     ) 
    [3] => Array 
     (
      [0] => 4 
      [1] => 660122Y 
     ) 
    [4] => Array 
     (
      [0] => 2 
      [1] => 790180X 
      [2] => 24mm 
     ) 
    [5] => Array 
     (
      [0] => 1 
      [1] => 225160Y 
     ) 
    [6] => Array 
     (
      [0] => 1 
      [1] => 244160Y 
     ) 
    [7] => Array 
     (
      [0] => 1 
      [1] => 225160Y 
     ) 
    [8] => Array 
     (
      [0] => 8 
      [1] => 954120Y 
     ) 
    [9] => Array 
     (
      [0] => 3 
      [1] => 072182X 
     ) 
) 

我想是这样的：

Array 
(
    [0] => Array 
     (
     [0] => 2 
     [1] => 790180X 
     [2] => 26mm 
     ) 

    [1] => Array 
     (
     [0] => 2 
     [1] => 790180X 
     [2] => 24mm 
     ) 

    [2] => Array 
     (
     [0] => 4 
     [1] => 762182Z 
     ) 

    [3] => Array 
     (
     [0] => 5 
     [1] => 072182X 
     ) 

    [4] => Array 
     (
     [0] => 4 
     [1] => 660122Y 
     ) 

    [5] => Array 
     (
     [0] => 2 
     [1] => 225160Y 
     ) 

    [6] => Array 
     (
     [0] => 1 
     [1] => 244160Y 
     ) 

    [7] => Array 
     (
     [0] => 8 
     [1] => 954120Y 
     ) 
) 

在短版的阵列：

Array    => TO =>  Array 
(         (
    [0] => 2:790180X:26mm   [0] => 2:790180X:26mm 
    [1] => 4:762182Z    [1] => 2:790180X:24mm 
    [2] => 2:072182X    [2] => 4:762182Z 
    [3] => 4:660122Y    [3] => 5:072182X 
    [4] => 2:790180X:24mm   [4] => 4:660122Y 
    [5] => 1:225160Y    [5] => 2:225160Y 
    [6] => 1:244160Y    [6] => 1:244160Y 
    [7] => 1:225160Y    [7] => 8:954120Y 
    [8] => 8:954120Y    ) 
    [9] => 3:072182X 
)

就总结到一个新的数组，使用各种“分组”字段作为新阵列中的键：

$sums = array(); 
foreach ($yourarray as $element) { 
    $sums[$element['dimension1']][$element['dimension2']]++; 
} 

对于需要'分组'的每个维度，您需要向$ sum数组添加一个键。
