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

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 https://stackoverflow.com/questions/2001281 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.

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</s> 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}" />

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));

You can get fans using new facebook search: https://www.facebook.com/search/321770180859/likers?ref=about

Use this.

https://www.facebook.com/browse/?type=page_fans&page_id=<your page id>

It will return up to 500 of the most recent likes.

http://www.facebook.com/browse/?type=page_fans&page_id=<your page id>&start=400

Each page will give you 100 fans. Change start value to (0, 100, 200, 300, 400) to get the first 500. If start is >= 401, the page will be blank :(

According to the Facebook documentation it's not possible to get all the fans of a page:

> Although you can't get a list of all the fans of a Facebook Page, you > can find out whether a specific person has liked a Page.

For s3m3n's answer, Facebook fans plugin (e.g. LAMODA) has limitation now, you get less and less new fans on continuous requests. You may try my modified PHP script to visualize results: https://gist.github.com/liruqi/7f425bd570fa8a7c73be#file-facebook_fans_by_plugin-php

Another approach is Facebook graph search. On search result page: People who like pages named "Lamoda" , open Chrome console and run JavaScript:

var run = 0;
var mails = {}
total = 3000; //滚动次数，可以自己根据情况定义
 
function getEmails (cont) {
	var friendbutton=cont.getElementsByClassName("_ohe");
	for(var i=0; i<friendbutton.length; i++) {
		var link = friendbutton[i].getAttribute("href");
 
		if(link && link.substr(0,25)=="https://www.facebook.com/") {
			var parser = document.createElement('a');
			parser.href = link;
			if (parser.pathname) {
				path = parser.pathname.substr(1);
				if (path == "profile.php") {
					search = parser.search.substr(1);
					var args = search.split('&');
					email = args[0].split('=')[1] + "@facebook.com\n";
				} else {
					email = parser.pathname.substr(1) + "@facebook.com\n";
				}
				if (mails[email] > 0) {
					continue;
				}
				mails[email] = 1;
				console.log(email);
			}
		}
	}
}
 
function moreScroll() {
	var text="";
	containerID = "BrowseResultsContainer"
	if (run > 0) {
		containerID = "fbBrowseScrollingPagerContainer" + (run-1);
	}
	var cont = document.getElementById(containerID);
	if (cont) {
		run++;
		var id = run - 2;
		if (id >= 0) {
			setTimeout(function() {
				containerID = "fbBrowseScrollingPagerContainer" + (id);
				var delcont = document.getElementById(containerID);
				if (delcont) {
				getEmails(delcont);
				delcont.parentNode.removeChild(delcont);
				}
				window.scrollTo(0, document.body.scrollHeight - 10);
			}, 1000);
		}
	} else {
		console.log("# " + containerID);
	}
	if (run < total) {
		window.scrollTo(0, document.body.scrollHeight + 10);
	}
	setTimeout(moreScroll, 2000);
}//1000为间隔时间，也可以根据情况定义
 
moreScroll();

It would load new fans and print user id/email, remove old DOM nodes to avoid page crash. You may find this script here

This page https://developers.facebook.com/docs/reference/fql/like/ wrote, you can't get fan list.

> "The Post, Video, Note, Link, Photo and Album Graph API objects > contain an equivalent connection called likes."

NOTE: fql like query is deprecated

Technically this FQL query should work, but for some reason Facebook disallows it because of a missing index. Not sure if that is because of policy or they just forgot.

SELECT uid FROM page_fans WHERE page_id="YOUR_PAGE_ID"

I created small tool called luster for downloading list of "likers" and "followers" of your Facebook page.

After download and unpack archive for your platform you can run it from terminal as

luster fans my-page-name

Where my-page-name is string identifier of your Facebook page.

You will be asked for email and password to your Facebook account. Note that this account need to have one of available page roles. Even Analyst is enough.

After while you should receive output similar to following

TIME,KIND,ID,NAME,LINK
1581665652,Like,111111111,John Doe,https://www.facebook.com/111111111
1581663355,Like,222222222,Kal Peterson,https://www.facebook.com/222222222
1581661970,Follow,333333333,Nikol Kus,https://www.facebook.com/333333333

This tool is based on reading table which can be found in Settings -> People and Other Pages section of your Facebook page.

Be aware that there is some limit up to 7k results from Facebook side. I tested it on two pages with more than 20k of fans and didn't get more then 7k results.
