Facebook api – Facebook like count url

As Facebook changed their API and deprecated the old one, I need to get data (likes count, share count, comment count) about single pages.

I figured out how to get data over Facebook graph (example link): 

https://graph.facebook.com/?fields=og_object{likes.limit(0).summary(true)},share&ids=http://www.businessinsider.com/airlines-dont-disclose-carrier-fee-that-inflates-ticket-prices-2016-9

But now I don’t know how to echo single data (likes count) in php. I tried with json, but had no sucsess:

$json = file_get_contents($xml);
$json_output = json_decode($json);

Any suggestions how to make this work?

    The results of json_decode() are Objects.
    So you can easily browse through like this:

    <?php    

$url = 'https://graph.facebook.com/?fields=og_object{likes.limit(0).summary(true)},share&ids=http://www.businessinsider.com/airlines-dont-disclose-carrier-fee-that-inflates-ticket-prices-2016-9';

$json = file_get_contents($url);
$json_output = json_decode($json);
foreach( $json_output as $site=>$data ){
    echo $site."n";
    echo $data->og_object->likes->summary->total_count;
}

?>

    The API Explorer adds the Access Token automatically, but you have to add it manually in your URL:

    https://graph.facebook.com/?fields=og_object{likes.limit(0).summary(true)},share&ids=http://www.businessinsider.com/airlines-dont-disclose-carrier-fee-that-inflates-ticket-prices-2016-9&access_token=xxx

    Result:

    {
  "http://www.businessinsider.com/airlines-dont-disclose-carrier-fee-that-inflates-ticket-prices-2016-9": {
    "og_object": {
      "likes": {
        "data": [
        ],
        "summary": {
          "total_count": 0,
          "can_like": true,
          "has_liked": false
        }
      },
      "id": "949055545223224"
    },
    "share": {
      "comment_count": 0,
      "share_count": 346
    },
    "id": "http://www.businessinsider.com/airlines-dont-disclose-carrier-fee-that-inflates-ticket-prices-2016-9"
  }
