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!

this question has answer here: java inner class , static nested class 23 answers i came across in java, know static nested class why create instance of 'static'. isn't whole idea of 'static' use without instance? understand concept of inner classes, why (and frankly how possible to) create 'instance' of 'static' member @ ? why this: 1- outerclass.staticnestedclass nestedobject = new outerclass.staticnestedclass(); 2- nestedobject.anestedclassmethod(); and not this: 1- outerclass outerinstance=new outerclass(); 2- outerinstance.staticnestedclass.anestedclassmethod(); use on inner classes, keyword static indicates can access inner class without instance of outer class. for example: public class outer { public static class inner { /* code here. */ } } with construction, can create instance of inn

JavaScript - Replace variable from string in all occurrences -

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
