Parsing All ItemPages

[haridarshan]

How to parse through all the Pages we get for any category and responsegroup

e.g.
$response = $amazonEcs->category('All')->responseGroup('ItemAttributes, Large, Medium')->search(array('Brand' => ));

$total_pages = $response['Items']['TotalPages'];

let say we got 100 pages each having 10 records. Now I would like to know how parse through all the remaining 99 pages.
