Question

 /* News Feed Data */
     public function newsFeed()
     {
        $db = getDB();
        $stmt = $db->prepare(\"SELECT user.id as id, user.nome as nome, app.id         


        

Answer 1

You have error in the binding. You have :uid in the query but :id in the binding. This should work:

    $stmt = $db->prepare("SELECT app_like.id , reaction.name from app_like, reaction WHERE reaction.id=app_like.reaction_id AND app_like.user_id=:uid  AND app_like.app_id=:id");  

    $stmt->execute(array(':uid' => $uid,
              ':id' => $msg_id));
