本文實例講述了Symfony2函數用法。分享給大家供大家參考,具體如下:
1.調用其他對象的方法。
例:
$grobal_func=$this->container->get('global_func'); //'global_func'函數所在的文件名 $lot_data=$global_func->getDataFromFile($parm1); //getDataFromFile函數名
2.數據庫的預備查詢
$conn = $this->em->getConnection(); $sql_user="select * from lot_user where user_name=:param1 and user_id=:param2 limit 1"; $params = array( 'param1' => $user, 'param2' => $uid ); $ready = $conn->prepare($sql_user); $ready->execute($params); $result_user = $ready->fetchAll();
3.數據庫回滾事件
$em->getConnection()->beginTransaction(); try{ $lotuser = new LotUser(); $lotuser->setId(0); $lotuser->setUserId($user_id); $lotuser->setUserName($user_name); $lotuser->setPassword($password); $lotuser->setUserTele($user_tele); $lotuser->setEmail($email); $lotuser->setRegDate($reg_date); $lotuser->setIdNumber($id_number); $lotuser->setRealUsername($real_username); $em->persist($lotuser); $em->flush(); $em->getConnection()->commit(); }catch(Exception $e){ $e->getConnection()->rollback(); }
希望本文所述對大家基於Symfony框架的PHP程序設計有所幫助。
