Although I myself would prefer it to be in this format:
$result = array();
foreach($rows as $row) {
$country = lookup($row[1]);
if(isset($result[$country])) {
$result[$country] += $row[0];
} else {
$result[$country] = $row[0];
}
}
Which would give:
array
(
INDIA => 112
CANADA => 272
//etc...
)
Then to use, just:
foreach($result as $country => $value) {
echo $country . ' ' . $value; // or whatever
}
