如何在php中求和数组值

Question

EDIT : now this is my real problem. here is my source, but my question is a bit different. if array key is same then sum value. my array is:

Array
(
    [one] => Array
        (
            [gozhi] => 2
            [uzorong] => 1
            [ngangla] => 4
            [langthel] => 5
        )

    [two] => Array
        (
            [gozhi] => 5
            [uzorong] => 0
            [ngangla] => 3
            [langthel] => 2
        )

    [three] => Array
        (
            [gozhi] => 3
            [uzorong] => 0
            [ngangla] => 1
            [langthel] => 3
        )
)

in above link, desired result is

Array
(
    [gozhi] => 10
    [uzorong] => 1
    [ngangla] => 8
    [langthel] => 10
)

but my desired result is

Array
(
    [one] => 12
    [two] => 10
    [three] => 7
)

Try this...

$sumArray = array();

foreach ($data as $key => $subArray) {


    $sumArray[$key]=array_sum(array_values($subArray));
  }


print_r($sumArray);

Array ( [one] => 12 [two] => 10 [three] => 7 )
