本文实例讲述了Symfony2函数用法。分享给大家供大家参考,具体如下:
1.调用其他对象的方法。
例:
$grobal_func=$this->container->get('global_func');//'global_func'函数所在的文件名$lot_data=$global_func->getDataFromFile($parm1);//getDataFromFile函数名
2.数据库的预备查询
$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.数据库回滚事件
$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();}
希望本文所述对大家基于Symfony框架的PHP程序设计有所帮助。
