How to get number of Facebook page likes

my following script doesn't show the number of fb-page-likes anymore...

$ch = curl_init("http://graph.facebook.com/FACEBOOKPAGE");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$raw = curl_exec($ch);
curl_close($ch);
$data = json_decode($raw);
$scm_fb = $data->likes;
echo $scm_fb;

I tried also the following code, but this also displays nothing... 

$page_id = "FACEBOOKPAGE"; 
$likes = 0; //Initialize the count

//Construct a Facebook URL
$json_url ='https://graph.facebook.com/'.$page_id.'';
$json = file_get_contents($json_url);
$json_output = json_decode($json);

//Extract the likes count from the JSON object
if($json_output->likes){
    $likes = $json_output->likes;
}

(I also tried the Facebook-Page-ID instead of the pagename, result is the same)

any suggestions?

You can get any graph object or url likes by parsing Facebook Like Widget source code using this php snippet:

<?php

    $id = "youtubetabapp";
    // customize: "https://facebook.com/[customize]"    
    $url = "https://facebook.com/$id"; // by name
    //$url = "https://facebook.com/282374908483303"; // or by id

    // customize: "locale=[customize]&" to your needs
    $ch = curl_init("https://www.facebook.com/v2.5/plugins/like.php?locale=$locale&href=".$url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_USERAGENT, 'Safari');
    $html = curl_exec($ch);

    //die( var_dump( $html ) ); // <- debug fetched data
    // have a look for the data you need and customize your regex pattern accordingly
    // "preg_match([customize], $html, $match);"
    preg_match("/([0-9,.]+[a-zA-Z,\S]) people like this./", $html, $match);
    $likes = $match[1];
    //$likes = str_replace(array(".", "K"), array("", "000"), $likes); // <- customize output | remove ".", replace "K" with "000"
    //$likes = (float)$likes; // <- customize output | change type to float, strips prepending non-digits (eg: "K") as well
    die( $likes );

?>

Compare to API methods you don't need to provide any tokens and it takes one single request. Based on my tests — you only need to keep locale parameter to make sure that you have constant source code for parsing.

You can use graph api to get the details of the page with corresponding access tokens. If you already have a valid access token, please use the below code to get the page details.

$fb_page = ''; 
$access_token = '';
$url = "https://graph.facebook.com/v2.2/".$fb_page.'?access_token='.$access_token;
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);   
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
$result = curl_exec($curl);  
curl_close($curl);
$details = json_decode($result,true);
echo "Likes:".$details['likes'];

You can't get any page like without providing your access_token to the Facebook Graph API.

Your URL should be like this

https://graph.facebook.com/v2.2/{YOUR_PAGE_ID}?fields=like&access_token={YOUR_ACCESS_TOKEN}

If you want to learn about how to use Graph API and how to generate your access_token try following links.
