这是我正在使用的数组（3层），我试图通过所有变量（不应添加月份）将第一个数组中第一个月到第二个数组中的第一个月的销售额（nosales）相加（应为150），依此类推，所以我只剩下一个两级数组，其中包含每个月的nosales、salevalue、salecost和saleprofit总数。
Array (
[0] => Array
(
[1] => Array
(
[month] => 1
[nosales] => 100
[salevalue] => 1200
[salecost] => 360
[saleprofit] => 840
)
[2] => Array
(
[month] => 2
[nosales] => 110
[salevalue] => 1320
[salecost] => 396
[saleprofit] => 924
)
)
[1] => Array
(
[1] => Array
(
[month] => 1
[nosales] => 50
[salevalue] => 350
[salecost] => 70
[saleprofit] => 280
)
[2] => Array
(
[month] => 2
[nosales] => 55
[salevalue] => 385
[salecost] => 77
[saleprofit] => 308
)
)
)
现在，我已经尝试过循环使用它们来将它们相加，但我遇到了一些错误。有人能帮忙吗？
以下是我目前正在使用的脚本：
$acc = array_shift($results_array);
foreach ($results_array as $val) {
foreach ($val as $v) {
foreach ($v as $key => $v){
$acc[$key] += $v;
}
}
}
提前感谢您的帮助！
这就是您想要做的吗？
