Newbie: can't access a return value.

Hi all, When I do this: $associacao_dao->listar($limit, $offset); I can var_dump the correct $limit. I can var_dump the correct $offset. I CAN'T access the object that I was hoping to get, called $records. After this, I was hoping to do var_dump($records); and see the stdClass object. Here is the listar method: public function listar($limit=null, $offset=null) { $query_str="SELECT * FROM associacao"; $stmt = $this->_dbh->prepare($query_str . ' LIMIT ?, ?'); $stmt->bindParam(1, $limit, PDO::PARAM_INT); $stmt->bindParam(2, $offset, PDO::PARAM_INT); $stmt->execute(); $records = $stmt->fetchAll(PDO::FETCH_OBJ); return $records; } Any help will be greatly appreciated. Thanks a lot in advance, Márcio
