oracle pdo Chinese Inquire

本人对数据库基本小白,PHP也是新手。现在用PDO远程访问oracle数据库时,表头是中文的,查询时就不出结果。比如$sql=select * from aaa where 站号= 1234 ;  返回是undefined index ......
求解。。。谢谢各位

你的表是用中文做文件名的吗?
打印出不加过滤条件时的查询结果(片段即可)

表名是英文,猜测可能是字符集的问题。执行select userenv('language') from dual后显示的是SIMPLIFIED CHINESE_CHINA.ZHS16GBK
用print_r打印了一个结果:
Array
(
    [ID] => 7883
    [???] => 3
    [??] => ?
    [????] => 0
)
怎么办啊大神?

噢,我问错了
你的字段名显然是中文的,这个就很麻烦了
你最好在控制台把字段名改成英文的

改不了啊大神,这个库不是我的,而且已经投入使用了,想改人家也不能同意。怎么办啊。。。

你的 dsn 是怎么写的?
new PDO('oci:dbname=//服务器名或ip:1521/实例名; charset=zhs16gbk', '用户名', '口令');
这个一定要有
因为你的字段名是中文的,所以字符集一定不能搞错
你若需要页面是 utf-8 的,那么只能读取后转码了
如果将中文字段名改成西文的,那么倒是可以改变 charset 来获取相应编码的数据

加了这句charset=zhs16gbk 出结果了!谢谢斑竹指导!

斑竹再请教一个问题,我想把查询结果转存到utf8的mysql,转码是哪个函数呀?
