HomeBackend DevelopmentPHP TutorialPDO读oracle中文查询问题

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


回复讨论(解决方案)

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?

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
