我有两个具有共同索引（教堂和办公室）的数组。我需要将第一个数组的总和“合并”到第二个数组中以获得所需的输出（见双线下方）。我不知道如何使用array_merge（）来做到这一点。任何帮助将不胜感激！
Array
(
[church] => Array
(
[total] => 77
)
[office] => Array
(
[total] => 202
)
)
Array
(
[church] => Array
(
[name] => Array
(
[0] => Bill
[1] => Sally
)
[addr] => Array
(
[0] => Address Same as Billing
[1] => Address Same as Billing
)
[message] => Array
(
[0] =>
[1] =>
)
[amount] => Array
(
[0] => 25
[1] => 50
)
)
[office] => Array
(
[name] => Array
(
[0] => Marta
[1] => Ruth
)
[addr] => Array
(
[0] => Address Same as Billing
[1] => Address Same as Billing
)
[message] => Array
(
[0] =>
[1] =>
)
[amount] => Array
(
[0] => 100
[1] => 100
)
)
)

答案 0 :(得分：0)
尝试这样的事情：
$ a = array（'church'=＆gt; array（'total'=＆gt; 5），'office'=＆gt; array（'total'=＆gt; 10））;
$ b = array（'church'=＆gt; array（'name'=＆gt;'church'），'office'=＆gt; array（'name'=＆gt;'office'））;
foreach（$ b as $ key =＆gt; $ value）{
$ b [$ key] = array_merge（$ a [$ key]，$ b [$ key]）;
}
