我必须总结给出的多维数组的数组键:

     Array
  (
  [0] => Array
    (
        [qty_of_leads_by_levels] => Array
            (
                [0] => 6054
                [1] => 454
                [2] => 113
                [3] => 85
                [4] => 42
                [5] => 21
                [6] => 5
                [7] => 1
                [8] => 1
            )

        [avg_conv_cof_arry] => Array
            (
                [0] => 0.08
                [1] => 0.1
                [2] => 0.34
                [3] => 0.25
                [4] => 0.28
                [5] => 0.15
                [6] => 0.16
                [7] => 0.49
                [8] => 0.52
            )

        [avg_deal_size] => 54545
        [total_bgt] => 143763
    )

[1] => Array
    (
        [qty_of_leads_by_levels] => Array
            (
                [0] => 11393
                [1] => 8144
                [2] => 6490
                [3] => 4868
                [4] => 2434
                [5] => 1217
                [6] => 305
                [7] => 76
                [8] => 57
            )

        [avg_conv_cof_arry] => Array
            (
                [0] => 0.41
                [1] => 0.42
                [2] => 0.68
                [3] => 0.5
                [4] => 0.55
                [5] => 0.3
                [6] => 0.31
                [7] => 0.98
                [8] => 1.01
            )

        [avg_deal_size] => 54545
        [total_bgt] => 297490245
    )

[2] => Array
    (
        [qty_of_leads_by_levels] => Array
            (
                [0] => 366
                [1] => 366
                [2] => 366
                [3] => 366
                [4] => 366
                [5] => 184
                [6] => 46
                [7] => 11
                [8] => 9
            )

        [avg_conv_cof_arry] => Array
            (
                [0] => 1
                [1] => 1
                [2] => 1
                [3] => 1
                [4] => 0.5
                [5] => 0.25
                [6] => 0.25
                [7] => 0.75
                [8] => 0.75
            )

        [avg_deal_size] => 54545     

        [total_bgt] => 1981167       
    )

)

在这里，我想得到数组键的总和，例如，键 [qty_of_leads_by_levels] 的值应该用相同的键和输出数组求和:

 [qty_of_leads_by_levels] => Array
    (
        [0] => 17814.49                   //sum
        [1] => 8965.52
        [2] => 6971.02
        [3] => 5320.75
        [4] => 2843.33
        [5] => 1422.7
        [6] => 356.72
        [7] => 90.22
        [8] => 69.28
    )      

 [avg_conv_cof_arry] => Array
            (
                [0] =>                 //sum
                [1] =>
                [2] => 
                [3] => 
                [4] => 
                [5] => 
                [6] => 
                [7] => 
                [8] =>
            )

      [avg_deal_size] =>                //sum

      [total_bgt] =>                    //sum

最佳答案

首先将您的关联数组分配给 $inputArray。

$sumArr = array();
    foreach($inputArray as $key1=>$value1){
    foreach($value1 as $key2=>$value2){
    if(is_array($value2)){
    foreach($value2 as $key3=>$value3){
        if(isset($sumArr[$key3])) {
                 $sumArr[$key3] = $sumArr[$key3] + $value3;
             } else {
                 $sumArr[$key3] = $value3;
             }

    }
    }
    }
    }

   print_r($sumArr);
