Well, then take what I gave you and do this:
$group[lookup($row[1])][] = $row[0];
foreach ( $group AS $x => $y )
{
$col1[] = $x;
$col2[] = array_sum($y);
}
In the end you will end up with this
<plaintext><?php
$data = array(
array(52, 'ARMENIA'),
array(215, 'CANADA'),
array(57, 'CANADA'),
array(261, 'COLOMBIA'),
array(53, 'EGYPT'),
array(62, 'INDIA'),
array(50, 'INDIA'),
);
foreach ( $data AS $row )
{
$group[$row[1]][] = $row[0];
}
print_r($group);
foreach ( $group AS $x => $y )
{
$col1[] = $x;
$col2[] = array_sum($y);
}
print_r($col1);
print_r($col2);
