Answer 1

Try this code, this will definitely work for you..
$removeKeys = array();
foreach($data['csv_data'] as $key => $val)///loop through array..
{
foreach($data['csv_data'] as $k => $v)
{
if($val[1] == $v[1] && $key != $k)////check if key 1 matches
{
if(!in_array($key,$removeKeys)) ////check if item is already added or not
{
$removeKeys[] = $k; ///push into removed keys because this is added into matched item
$data['csv_data'][$key][7]+=$data['csv_data'][$k][7];
$data['csv_data'][$key][8]+=$data['csv_data'][$k][8];
}
}
}
}
foreach($removeKeys as $rk)
{
unset($data['csv_data'][$rk]); ////remove all the keys in removeKeys
}
print_r($data['csv_data']);///your desired output...
This will give you :
Array
(
[0] => Array
(
[0] => CAM
[1] => Partner
[2] => Division
[3] => Domain
[4] => Year
[5] => Quarter
