php array, loop to get the exact value

Question

I have this code right here, where the $friends variable is an array with an output like this:

{
  \"id\": \"1149862205\",
  \"name\": \"name\",

You need to check inside you loop to get the ones that don't like.

$return = '';
$friends = $facebook->api('/me/friends');
if (!empty($friends['data'])) {
    $size = variable_get('facebook_graph_pic_size_nodes','square');
    $protocol = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') ? 'https' : 'http';
    foreach ($friends['data'] as $data) {
        $fbid = $data['id'];
        $fbfriendlikes[$fbid]=$facebook->api('/'.$fbid.'/likes'); 
        $fbname = $data['name'];
        $path = $protocol . '://graph.facebook.com/' . $fbid . '/picture?type=' . $size;
        $image = theme('image', array('path' => $path, 'alt' => $fbname));

        foreach($fbfriendlikes['data'] as $like) {
            $likes = false; // set var to check for like
            if($like['id'] == '184759054887922') { // check if they liked it
                $likes = true; // set var to true because they liked it
            }
            if (!$likes) { // test var to see if false (they did not like)
                // print this if they did NOT like it, otherwise do nothing
                $return .= '
'.$image.'
';
                $link = ''.$fbname.'';    
                $return .= '
'.$link.'
';
            }
        }// go on to next in loop

    }
    echo $return;
}
