Pagination Example

This example covers basic cursor pagination with the Facebook SDK for PHP.

Example

The Graph API supports several methods to paginate over response data. The PHP SDK supports cursor-based pagination out of the box. It does all the heavy lifting of managing page cursors for you.

In this example we'll pull five entries from a user's feed (assuming the user approved the read_stream permission for your app). Then we'll use the next() method to grab the next page of results. Naturally you'd provide some sort of pagination navigation in your app, but this is just an example to get you started.

$fb = new Facebook\Facebook([
  'app_id' => '{app-id}',
  'app_secret' => '{app-secret}',
  'default_graph_version' => 'v10.0',
  ]);

try {
  // Requires the "read_stream" permission
  $response = $fb->get('/me/feed?fields=id,message&limit=5');
} catch(Facebook\Exception\ResponseException $e) {
  // When Graph returns an error
  echo 'Graph returned an error: ' . $e->getMessage();
  exit;
} catch(Facebook\Exception\SDKException $e) {
  // When validation fails or other local issues
  echo 'Facebook SDK returned an error: ' . $e->getMessage();
  exit;
}

// Page 1
$feedEdge = $response->getGraphEdge();

foreach ($feedEdge as $status) {
  var_dump($status->asArray());
}

// Page 2 (next 5 results)
$nextFeed = $fb->next($feedEdge);

foreach ($nextFeed as $status) {
  var_dump($status->asArray());
}
