An alternative way is to use a provider such as Dialogfeed.
It gives a JSON (or XML or JSONP) social media feed of Facebook, Twitter, Linkedin, Instagram, Youtube, RSS channels. You can do on it requests (offset, timestamp...)
Features are described at http://www.dialogfeed.com/facebook-twitter-json-feed/

You also should mention your's a PAID SERVICE. Its a shame you advertise your paid service in a free snippet.

On facebook.php at line 48 I had to modify it to be:

$authResponse = json_decode($authentication);
$response = file_get_contents("https://graph.facebook.com/{$feed}/feed?access_token={$authResponse->access_token}&limit={$maximum}");

Hope that helps someone.

Hi, I'm wondering how to limit the data we get from Twitter? I only want to have "Tweets" and not the "Replies" part, but when I try to add "exclude_replies=true" and it returns 302.
