I'm looking for a short way of suming the indexes of two arrays and
returning one array as the result. I'm not referring to what
array_sum() is capable of doing. Below will get it done; but is there
any built in function doing the same??
function sum_by_index($array1,$array2) {
for ($i = 0; $i <= (count($array1) -1); $i++) {
$temp[$i] = $array1[$i] + $array2[$i];
}
return $temp;
}//note both $array1 and $array2 are to be of the same size
Regards,
Gerard.
