如何對(duì)多維數(shù)組中的所有列值進(jìn)行求和？如何通過關(guān)聯(lián)鍵添加所有列值？請(qǐng)注意[gozhi]關(guān)鍵是動(dòng)態(tài).輸入數(shù)組：Array
(
[0] => Array
(
[gozhi] => 2
[uzorong] => 1
[ngangla] => 4
[langthel] => 5
)
[1] => Array
(
[gozhi] => 5
[uzorong] => 0
[ngangla] => 3
[langthel] => 2
)
[2] => Array
(
[gozhi] => 3
[uzorong] => 0
[ngangla] => 1
[langthel] => 3
)
)預(yù)期結(jié)果：Array
(
[gozhi] => 10
[uzorong] => 1
[ngangla] => 8
[langthel] => 10
)
