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：
例:
container->get('global_func');
//'global_func'函数所在的文件名
$lot_data=$global_func->getDataFromFile($parm1);
//getDataFromFile函数名
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
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。
