Facebook API: Get fans of / people who like a page

Question

I'd like to get a list of users who like a certain page or a fan of it.

The FB API documentation states that you can only get the count of the fans of a certain page using the social graph, but not a list of the fans.

A discussion here Retrieve Facebook Fan Names suggests that one could use an FQL query like SELECT user_id FROM like WHERE object_id="YOUR PAGE ID" to get the number of people who liked the page, but for the same page, it gives an empty response "{}".

So I was wondering if anyone has an idea if this can be done.

Answer 1

There is a "way" to get some part of fan list with their profile ids of some fanpage without token.

1. Get id of a fanpage with public graph data: http://graph.facebook.com/cocacola - Coca-Cola has 40796308305. UPDATE 2016.04.30: Facebook now requires access token to get page_id through graph so you can parse fanpage HTML syntax to get this id without any authorization from https://www.facebook.com/{PAGENAME} as in example below based on og tags present on the fanpage.
2. Get Coca-Cola's "like plugin" iframe display directly with some modified params: http://www.facebook.com/plugins/fan.php?connections=100&id=40796308305
3. Now check the page sources, there are a lot of fans with links to their profiles, where you can find their profile ids or nicknames like: http://www.facebook.com/michal.semeniuk .
4. If you are interested only in profile ids use the graph api again - it will give you profile id directly: http://graph.facebook.com/michal.semeniuk UPDATE 2016.04.30: Facebook now requires access token to get such info. You can parse profile HTML syntax, just like in the first step meta tag is your best friend: <meta property="al:android:url" content="fb://profile/{PROFILE_ID}" />

And now is the best part: try to refresh (F5) the link in point 2.. There is a new full set of another fans of Coca-Cola. Take only uniques and you will be able to get some nice, almost full list of fans.

Why don't you use my ready PHP script to fetch some fans? :)

UPDATE 2016.04.30: Updated example script to use new methods after Facebook started to require access token to get public data from graph api.

function fetch_fb_fans($fanpage_name, $no_of_retries = 10, $pause = 500000 /* 500ms */){     $ret = array();     // prepare real like user agent and accept headers     $context = stream_context_create(array('http' => array('header' => 'User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/49.0.2623.108 Chrome/49.0.2623.108 Safari/537.36\r\nAccept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8\r\nAccept-encoding: gzip, deflate, sdch\r\nAccept-language: en-US,en;q=0.8,pl;q=0.6\r\n')));     // get page id from facebook html og tags for mobile apps     $fanpage_html = file_get_contents('https://www.facebook.com/' . $fanpage_name, false, $context);     if(!preg_match('{fb://page/(\d+)}', $fanpage_html, $id_matches)){         // invalid fanpage name         return $ret;     }     $url = 'http://www.facebook.com/plugins/fan.php?connections=100&id=' . $id_matches[1];     for($a = 0; $a < $no_of_retries; $a++){         $like_html = file_get_contents($url, false, $context);         preg_match_all('{href="https?://www\.facebook\.com/([a-zA-Z0-9\._-]+)" class="link" data-jsid="anchor" target="_blank"}', $like_html, $matches);         if(empty($matches[1])){             // failed to fetch any fans - convert returning array, cause it might be not empty             return array_keys($ret);         }else{             // merge profiles as array keys so they will stay unique             $ret = array_merge($ret, array_flip($matches[1]));         }         // don't get banned as flooder         usleep($pause);     }     return array_keys($ret); }  print_r(fetch_fb_fans('TigerPolska', 2, 400000));
