php - 定位多维数组中的键

Question

我有一个像这样的数组。

Array
(
[162 D Dr.] => Array
    (
        [smi_discover] => 0
        [smi_totalmonthccsales] => 12568
        [smi_amex] => 0
        [smi_visamc] => 12568
        [smi_ebt] => 0
        [smi_includeindeal] => 0
        [smi_debit] => 0
        [smi_batches] => 7
    )
 [16ee22 D Dr.] => Array
    (
        [smi_discover] => 0
        [smi_totalmonthccsales] => 125368
        [smi_amex] => 0
        [smi_visamc] => 12568
        [smi_ebt] => 0
        [smi_includeindeal] => 0
        [smi_debit] => 0
        [smi_batches] => 7
    )
)

这把钥匙 [162 D Dr.] 可以是任何东西。[16e2 D Dree]，[332 D44 Drdds]。

我如何循环遍历并添加 smi_totalmonthccsales 并将其添加到父数组中，所以我最终会得到这样的结果

['total'] = sum of smi_totalmonthccsales in both address arrays
[162 D Dr.] => Array
    (
        [smi_discover] => 0
        [smi_totalmonthccsales] => 12568
        [smi_amex] => 0
        [smi_visamc] => 12568
        [smi_ebt] => 0
        [smi_includeindeal] => 0
        [smi_debit] => 0
        [smi_batches] => 7
    )

我试过了

foreach($newnewArr as $key) {
    if(isset($key['smi_totalmonthccsales']) && isset($key)){
        $ccArray[$key]['total'] +=$key['smi_totalmonthccsales'];
    } else {
        $ccArray[$key]['total'] = 0;
    }
}

Answer 1

之后就设置好了。

$total = 0;

foreach($arr as $key => $value) {
    $total += $value['smi_totalmonthccsales'];
}

$arr['total'] = $total;

你想要一个运行总数？好的...

$total = 0;

foreach($arr as &$value) {
    $total += $value['smi_totalmonthccsales'];
    $value['total'] = $total;
}
