How to call an item from graph api fb?

Question

I want to select an specific field.item from the requested api call and echo it.for example something like this:

$getlike = $facebook->api("/fql?q=SELECT%20like_info%20FROM%20stream%20WHERE%20post_id=".$id);

$getcm = $getlike['data']['like_info']['user_likes'];
echo $getcm;

The JSON for the above code:

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

When i echo the $getcm,it wont return anything.Is there anything wrong?

Answer 1

data is an array; so you should fetch it like-

$getcm = $getlike['data'][0]['like_info']['user_likes'];
echo $getcm;
