我有这个数组：
Array
(
[0] => Array
(
[id] => 1
[amount_positive] => 10.00
[negative_sum] => -5,7
[negative] => Array
(
[0] => Array
(
[amount] => -3.00
)
[1] => Array
(
[amount] => -2.00
)
[2] => Array
(
[amount] => -0.70
)
)
)
[1] => Array
(
[id] => 13
[amount_positive] => 6.00
[negative_sum] => -7
[negative] => Array
(
[0] => Array
(
[amount] => -7
)
)
)
)
您可以注意到，键0的正数为+10.00，负数为-5.7（它们是货币交易）。
Key 1有+13和-7。
基本上，我需要迭代到数组并在键0下移动4.30，取自键1的NEGATIVE。
这必须是最后一个数组：
Array
(
[0] => Array
(
[id] => 1
[amount_positive] => 10.00
[negative_sum] => -10.00
[negative] => Array
(
[0] => Array
(
[amount] => -3.00
)
[1] => Array
(
[amount] => -2.00
)
[2] => Array
(
[amount] => -0.70
)
[3] => Array
(
[amount] => -4.30
)
)
)
[1] => Array
(
[id] => 13
[amount_positive] => 6.00
[negative_sum] => -2.70
[negative] => Array
(
[0] => Array
(
[amount] => -2.70
)
)
)
)
答案 0 :(得分：0)
如果您需要在此特定阵列上执行转换的代码（您知道数组索引），以下内容将执行您想要的操作：
$expense = -4.30;
$your_array[0]['negative'][] = ['amount' => $expense];
$your_array[0]['negative_sum'] += $expense;
$your_array[1]['negative'][0]['amount'] -= $expense;
$your_array[1]['negative_sum'] -= $expense;
如果你想要一个更多的＆＃34;一般＆＃34;对于任意索引和任意amount条目的方法，您需要从更广泛的角度重新解释您的问题。
