Subtracting one array from another

Question

I want to subtract one array from another .

for example I have 2 arrays.

Array
(
    [0] => 251
    [1] => 251
    [2] => 130
)


 Array
    (
        [0] => 13
        [1] => 13
        [2] => 50
    )

The resulting array has to be

Array
    (
        [0] => 238
        [1] => 238
        [2] => 80
    )

Any sort of help on this is appreciated .

Answer 1

Try this :

$array1  = array(251, 251, 130);
$array2  = array( 13,  13,  50);
$res     = array();
for($i=0;$i<count($array1);$i++){
   $res[$i] = $array1[$i]-$array2[$i];
}

echo "<pre>";
print_r($res);
