文章收藏了一些常用的解决php保存中文sql server 2008里出现乱码办法,有碰到同类问题的朋友可参考本文章。

今天使用php操作数据库时发现插入SQL Server 2008数据库里的中文字段出现乱码,下面是我一开始时的一些情况:

开发环境是php5.3.3+Apache2.2.17+SQL Server 2008,php脚本文件的编码是utf-8,传给数据库的编码是GB2312(SQL Server的默认字符编码可能是这个,我不肯定),我用的是微软官方提供的SQLSRV库来连接数据库的(PS:SQL Server 2005开始已经不支持用mssql.dll来连接了),故使用sqlsrv_query($conn, "set names GB2312");语句来设置传给数据库的编码格式的,sql语句这样写了:insert into Opinion (content) values ('aaa中文内容');

  运行这条sql语句,发现执行不成功,用sqlsrv_errors()函数来输出错误信息,得到如下结果:

 代码如下 复制代码
Array ( [0] => Array ( [0] => IMSSP [SQLSTATE] => IMSSP [1] => -46 [code] => -46 [2] => An error occurred translating the query string to UTF-16: �ڶ��ֽڵ�Ŀ�����ҳ�У�û�д� Unicode �ַ����ӳ�䵽���ַ� . [message] => An error occurred translating the query string to UTF-16: �ڶ��ֽڵ�Ŀ�����ҳ�У�û�д� Unicode �ַ����ӳ�䵽���ַ� . ) )

  这是在网页上显示的结果,上面的乱码是原封不动copy下来的。从 “An error occurred translating the query string to UTF-16”可以看出是字符编码转换有问题导致的。于是我使用php的iconv函数来对中文进行强制编码转换,然后执行sql语句,代码如下:

 代码如下 复制代码
$string = iconv('utf-8', 'GB2312//IGNORE', 'aaa中文内容');
$sql    = "insert into Opinion (content) values ( $string)";

  这时候又报错了,错误信息如下:

 代码如下 复制代码
Array ( [0] => Array ( [0] => 42S22 [SQLSTATE] => 42S22 [1] => 207 [code] => 207 [2] => [Microsoft][SQL Server Native Client 10.0][SQL Server]���� 'aaa��������' ���� [message] => [Microsoft][SQL Server Native Client 10.0][SQL Server]���� 'aaa��������' ���� ) )

  这个错误信息看不出什么头绪,我又把sql语句输出到网页上看一下是不是sql语句写错了,输出结果如下:

 代码如下 复制代码
insert into Opinion (content) values ( aaa��������)

  咋一看好像没问题,其实是有问题的,注意到后面那个括号里的参数是应该用引号来括起来的(表示它是一个字符串),所以我又修改了sql语句,代码如下:

 代码如下 复制代码
$sql = "insert into Opinion (content) values ( '".$string."')";   为了看清楚我放大点

用单引号把$string括起来,这样之后执行sql语句成功,并且数据库里保存的中文没有乱码。


参考其它的解决办法


若数据库的编码为GB2312,怎样在yii中进行配置才能使得页面的数据显示正常,并且数据库中的数据不能出现乱码:

方法一:

1. yii默认的编码方式是utf-8, 若想改变其编码方式需要在main.php文件中加上'charset'=>'GB2312', 这样才能改变函数的输出的编码方式
2. sql server 2000 的编码方式默认为本地GB2312编码方式, 对数据库进行操作时要注意编码的方式
3. web页面的编码相应的需要变为GB2312
4. 文件保存时需要保存为GB2312编码,这样php文件中的中文字符才能正常解析

方法二:

1. 通过iconv函数对数据进行转码

 代码如下 复制代码
iconv('GB2312','UTF-8',$data)

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
