-$api->setUserId(184263228);
-$api->setAccessToken('1234578.abcabc.abcabcabcabcabcabcabcabcabcabc');
-
-$feed = $api->getFeed();
-
-$endCursor = $feed->getMaxId();
-
-// Second call : 
-
-$api = new Api();
-$api->setUserId(184263228);
-$api->setAccessToken('1234578.abcabc.abcabcabcabcabcabcabcabcabcabc');
-$api->setMaxId('1230468487398454311_184263228');
