Use array_sum():

$output = array();
foreach ($array as $k => $a) {
  $output[$k] = array_sum($a);
}

How about :

foreach ($myArray as $k=>$subArray) {   
    $sumArray[$k] = 0;   
    foreach ($subArray as $id=>$value) {
       $sumArray[$k]+=$value;   
    }
}

as $k represents your country, you sum all values of it's subarray and store it in a map which has a key with the name stored in $k.
