json api graph call does not return anything?

Question

i am fetching users fb newfeed and i wanted get check wether user has liked the post or not by using user_likes and the problem is that the following code wont return anything :

$getlike = $facebook->api("/fql?q=SELECT like_info FROM stream WHERE post_id=" . $id);
$checklike = $getlike['data'][0]['like_info']['user_likes'];

here is the complete file: testone.php the problem is that the fql and calling user_likes wont return anything. i want to check wether user has liked the post already OR how can i get the value for user_likes.

JSON from fb :

{
  "data": [
    {
      "like_info": {
        "can_like": true, 
        "like_count": 70, 
        "user_likes": false
      }
    }
  ]
}

is my technique right?do i need access code or something?

Answer 1

If you are getting the value of $getlike, you can check the value of user_likes like this (since it is of type boolean)-

if($getlike['data'][0]['like_info']['user_likes'])
{
    echo "true";    
}
else 
{
    echo "false";   
}
