php - What's method for checking user fan of a page in GRAPH API? -

-

in graph api, pages.isfan method not working, what's method checking user fan of page in graph api?

thanks.

update 2:
check if current user fan of facebook page on landing @ tab check answer.

update:
can use likes connection check if user fan of page: 

https://graph.facebook.com/me/likes/page_id &access_token=access_token

this return either empty data array: 

array (     [data] => array         (         )  )

or if fan: 

array (     [data] => array         (             [0] => array                 (                     [name] => real madrid c.f.                     [category] => professional sports team                     [id] => 19034719952                     [created_time] => 2011-05-03t20:53:26+0000                 )          )  )

so how check using php-sdk: 

<?php require '../src/facebook.php';  // create our application instance (replace appid , secret). $facebook = new facebook(array(   'appid' => 'app_id',   'secret' => 'app_secret', ));  $user = $facebook->getuser();  if ($user) {   try {     $likes = $facebook->api("/me/likes/page_id");     if( !empty($likes['data']) )         echo "i like!";     else         echo "not fan!";   } catch (facebookapiexception $e) {     error_log($e);     $user = null;   } }  if ($user) {   $logouturl = $facebook->getlogouturl(); } else {   $loginurl = $facebook->getloginurl(array(     'scope' => 'user_likes'   )); }  // rest of code here ?>

similar script usingjs-sdk: 

fb.api('/me/likes/page_id',function(response) {     if( response.data ) {         if( !isempty(response.data) )             alert('you fan!');         else             alert('not fan!');     } else {         alert('error!');     } });  // function check empty object function isempty(obj) {     for(var prop in obj) {         if(obj.hasownproperty(prop))             return false;     }      return true; }

code taken tutorial.

while pages.isfan still working me, can use fql page_fan table new php-sdk: 

$result = $facebook->api(array(     "method"    => "fql.query",     "query"     => "select uid page_fan uid=$user_id , page_id=$page_id" )); if(!empty($result)) // array not empty, user fan!     echo "$user_id fan!";

from documentation:

to read page_fan table need:

  • any valid access_token if public (visible on facebook).
  • user_likes permissions if querying current user.
  • friends_likes permissions if querying user's friend.

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
