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][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);
