php 根据键名分类求和,二维数组根据键值相加
怎樣根據每一個數組的鍵值相加？
Array
(
[0] => Array
(
[reg] => 0
[regs] => 0
[login] => 7
[pay] => 0
[buy] => 4
[payment] => 11334.00
[recharge] => 1
[rechargea] => 3600.00
)
[1] => Array
(
[reg] => 1
[regs] => 0
[login] => 22
[pay] => 0
[buy] => 0
[payment] => 0.00
[recharge] => 0
[rechargea] => 0.00
)
[2] => Array
(
[reg] => 0
[regs] => 0
[login] => 5
[pay] => 0
[buy] => 1
[payment] => 376.00
[recharge] => 0
[rechargea] => 0.00
)
[3] => Array
(
[reg] => 0
[regs] => 0
[login] => 3
[pay] => 0
[buy] => 0
[payment] => 0.00
[recharge] => 0
[rechargea] => 0.00
)
[4] => Array
(
[reg] => 0
[regs] => 0
[login] => 2
[pay] => 0
[buy] => 1
[payment] => 1787.00
[recharge] => 0
[rechargea] => 0.00
)
[5] => Array
(
[reg] => 1
[regs] => 0
[login] => 7
[pay] => 0
[buy] => 0
[payment] => 0.00
[recharge] => 0
[rechargea] => 0.00
)
[6] => Array
(
[reg] => 0
[regs] => 0
[login] => 1
[pay] => 0
[buy] => 0
[payment] => 0.00
[recharge] => 0
[rechargea] => 0.00
)
[7] => Array
(
[reg] => 0
[regs] => 0
[login] => 0
[pay] => 0
[buy] => 0
[payment] => 0.00
[recharge] => 0
[rechargea] => 0.00
)
)

array[0][reg] + array[1][reg]+ array[2][reg]......
array[0][login] + array[1][login]+ array[2][login]......
每一個數組相同鍵值的相加在一起。
$data = array(0 => array('a'=>1, 'b' => 2), 1 => array('a' => 3, 'c' => 4));$result = array();foreach($data as $index => $arr){ foreach($arr as $key => $value){ $result[$key] += $value; }}print_r($result);
