Array
(
[A.txt] => 72
[B.txt] => 27
[C.txt] => 12
)

This is what I want to do:
1 sum all those values and give them to the first key which is [A.txt].
2. remove the [A.txt] then sum [b.txt] and [C.txt] then give the value to key [B.txt].
3 Remove [A.txt],[B.txt] then sum whatever is left and give it to [C.txt].

so that my result will look like this

Array
(
[A.txt] => 111,
[B.txt] => 39,
[C.txt] => 12
)

Language: PHP

Thanks a lot.

$temp_result=array();
$array=Array("[A.txt]" => 72,"[B.txt]" => 27,"[C.txt]" => 12);

$firstKey = array_key_first($array);
$sum=array_sum($array);
$temp_result=array_merge($temp_result,array($firstKey => $sum));


$output = array_slice($array, 1);
$secondKey = array_key_first($output);
$sum=array_sum($output);
$temp_result=array_merge($temp_result,array($secondKey => $sum));



$output = array_slice($array, 2);
$thirdKey = array_key_first($output);
$sum=array_sum($output);
$temp_result=array_merge($temp_result,array($thirdKey => $sum));


print_r($temp_result);
