Вот что я сделал, чтобы получить информацию о сообщениях ... сырая, но она работает.Обратите внимание, что акции любят комментарии и реакции на один уровень глубже в объекте JSON
$posts = json_decode($output); // from FB Graph v2.8 API call
foreach($posts->data as $post)
{
echo "MESSAGE: ", $post->message, "<br>";
echo "NAME: ", $post->name, "<br>";
echo "TYPE: ", $post->type, "<br>";
echo "ID: ", $post->id, "<br>";
echo "LINK: ", $post->link, "<br>";
echo "PERMALINK: ", $post->permalink_url, "<br>";
echo "CREATED: ", $post->created_time, "<br>";
if($post->shares->count == "") { $shares = "0"; } else { $shares = $post->shares->count; }
echo "SHARES: ", $shares, "<br>";
if($post->reactions->summary->total_count == "") { $reactions = "0"; } else { $reactions = $post->reactions->summary->total_count; }
echo "REACTIONS: ", $reactions, "<br>";
if($post->comments->summary->total_count == "") { $comments = "0"; } else { $comments = $post->comments->summary->total_count; }
echo "COMMENTS: ", $comments, "<br>";
if($post->likes->summary->total_count == "") { $likes = "0"; } else { $likes = $post->likes->summary->total_count; }
echo "LIKES: ", $likes, "<br>";
echo "<br><br>";
}
