二维数组根据键值相加

怎样根据每一个数组的键值相加？


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]......

每一个数组相同键值的相加在一起。

$data = array(0 => array('a'=>1, 'b' => 2), 1 => array('a' => 3, 'c' => 4));$result = array();foreach($data as $index => $arr){    foreach($arr as $key => $value){        $result[$key] += $value;    }}print_r($result);
