pagination within the facebook API (photos) - php

Question

I'm currently developing a facebook app that needs access to a users photos. It needs to loop through all of the users active photos however I'm having some trouble with the pagination aspect of the feed. I get results from the API like
stdClass Object
(
[data] => Array
(
[0] => stdClass Object
(
[id] => 10151796309135076
[from] => stdClass Object
(
[name] => Daniel Benzie
[id] => 762525075
)
)
)
)
obviosuly the above is an excerpt and then down the bottom there is a section for next and previous pages.
[previous] => https://graph.facebook.com/762525075/photos?access_token=xxxxxxx&limit=25&since=1338985293&__previous=1
[next] => https://graph.facebook.com/762525075/photos?access_token=xxxxx&limit=25&until=1332002972
this is always set- does anyone know the best way to loop through the photos in this case? thanks in advance (:

Answer 1

Keep calling the next url until there is no more data
while ($some_photos['data'])
{
$all_photos = array_merge( $all_photos, $some_photos['data'] );
$paging = $some_photos['paging'];
$next = $paging['next'];
$query = parse_url($next, PHP_URL_QUERY);
parse_str($query, $par);
$some_photos = $facebook->api(
$user_id."/photos", 'GET', array(
'limit' => $par['limit'],
'until' => $par['until'] ));
}
