php - Facebook Graph API call returns false -

-

i'm amateur programmer trying fetch facebook page likes webpage since not want facebooks standard plugin. after lot of research , testing found out right call make is:

https://graph.facebook.com/{page_id}?access_token={app_id}|{app_secret}&fields=fan_count

using in web browser works great , fan count in json.

my problem when try make call using either curl or file_get_contents inside php script dont seem back. after doing var_dump bool(false) back. , after doing print_r nothing.

is facebook somehow blocking calls or wrong? have tried multiple ways found online , none works. 1 of examples:

<?php     $json_url = "https://graph.facebook.com/xxxxxxxxxxx?access_token=xxxxxxxxxxxxx&fields=fan_count";     $json = file_get_contents($json_url);     $json = json_decode($json, true);      print_r($json);      echo "number of likes : ". $json[0]->fan_count; ?>

this another:

<?php      $ch = curl_init("https://graph.facebook.com/v2.6/xxxxxxxxxxxxx?access_token=xxxxxxxxxxxx&fields=fan_count");      curl_setopt( $ch, curlopt_post, false );      curl_setopt( $ch, curlopt_followlocation, true );      curl_setopt($ch, curlopt_useragent, "mozilla/5.0 (windows; u; windows nt 5.0; en-us; rv:1.7.12) gecko/20050915 firefox/1.0.7");      curl_setopt( $ch, curlopt_header, false );      curl_setopt( $ch, curlopt_returntransfer, true );      $data = curl_exec( $ch );      echo $data; ?>

the problem seem right after graph call. can't figure out why, appreciated :) thanks!
