Can I post on Facebook bold text with PHP SDK? -

i have function:

public function posttofacebookwall($title, $uri, $desc, $msg = null, $pic = null, $caption = null, $action_name = null, $action_link = null, $uid = 'me') {     try {         $data = array(             'name' => $title,             'link' => $uri,             'description' => $desc                     );          if ($pic) {             $data['picture'] = $pic;         }          if ($caption) {             $data['message'] = $caption;         }          if ($action_name) {             $data['actions'] = json_encode(array('name' => $action_name, 'link' => $action_link));         }          app::facebook()->api("/$uid/feed", "post", $data);     } catch (exception $e) {         return false;     }      return true; } 

it posts text , link below. can somehow tell facebook make text bold? make caption bold, not know how. if put inside or tags, on facebook see texts like:

<strong>this text</strong>  <b>this text</b> 

instead of making text bold. how can make text bold?

this isn't possible. markup text available facebook notes , documents in facebook groups.
