            $rh = $this->db->prepare('SELECT * FROM app');
            //$rh->bindParam(':userOwnerId', $_SESSION['userId'], PDO::PARAM_STR);
            $rh->execute();
            $appData['App'] = $rh->fetchAll();
            $this->smartyTemplate->assign('appData', $appData);
            $this->smartyTemplate->assign('request', $requestvars);
            $this->smartyTemplate->assign('homePath', APP_ROOT_DIR);

  "lastUpdateTime": "1471848392"
 }
Solution

  • Use PDO::FETCH_ASSOC. The default for fetchAll() is PDO::FETCH_BOTH, which returns an array with both numeric and named indexes.

            $appData['App'] = $rh->fetchAll(PDO::FETCH_ASSOC);
