解决php mysql查询插入中文乱码问题

   一.中文问题其实就是经统一编码了否则就会乱码

  1.数据库与php页面编码统一

  2.数据库数据表字段与页面编码统一

  如果做到上面两种就不存在中文乱码问题了,那么我们来看mysql中文乱码问题解决例子

  1.我的mysql表如下

  --

  -- 表的结构 `useradmin`

  --

代码如下  

CREATE TABLE IF NOT EXISTS `userain` (
`id` int(4) NOT NULL AUTO_INCREMENT,
`username` varchar(20) DEFAULT NULL,
`userpass` varchar(40) DEFAULT NULL,
`logins` int(4) NOT NULL DEFAULT '0' COMMENT '登陆次数',
`logintime` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
`mid` char(1) NOT NULL DEFAULT '0',
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=7 ;

  上面所有的都是utf8编码了,这样我来测试一个中文

代码如下  

INSERT INTO `userain` (`id`, `我是中文`, `userpass`, `logins`, `logintime`, `mid`) VALUES
(1, 'admin', '7c1f03139281878059b909c42ccf2f6a', 0, '2010-04-14 14:20:26', '1');

  我说可以正常进入也有人说肯定不行其实关键不在sql语句了,重点在于php连接mysql数据时的编码设置,如下。

  页面编辑为gbk

代码如下  

//配置mysql数据库连接参数
$db = mysql_connect("localhost", "user","password");
mysql_select_db("message",$db);
//在执行sql语句之前加上下面这一行

?>

  连接数据库之后提交肯定是乱码或保存不进行了,如果要解决这个mysql中文乱码问题很简单在查询处的

代码如下  

//配置mysql数据库连接参数
$db = mysql_connect(www.45it.net, "user","password");
mysql_select_db("message",$db);
//在执行sql语句之前加上下面这一行
mysql_query("SET NAMES 'utf8'",$db);

  这样再提交你会发现就算你的页面是gbk的提交的数据保存也会成功哦

  ps:对于ajax我们就一定要用uft8了,因为ajax只支持uft8模式传输数据。
