当从php页面提交插入记录并返回页面时，显示的提交内容没有乱码，只是在Dreamweaver制作时写入的中文是乱码；
然后打开http://localhost/phpmyadmin/页面查看数据库，发现刚才输入的中文显示为乱码；
这个时候，我在数据库里修改刚才输入的中文并保存，这时数据库能显示的是中文，但回到在php页面运行预览（F12）时，在数据库里修改的那部分出现的是很多问号（?），其他没有修改的内容没有变化。请各位高手出手相助！该如何修改才不会乱码？
1..安装的是appserv-win32-2.5.9及Dreamweaver CS3
2..在MySQL Command Line Client输入以下命令时：
mysql> SHOW CHARACTER SET;

3..在Dreamweaver CS3新建php页面时有以下代码：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
4..进入http://localhost/phpmyadmin/页面显示：
localhost
服务器版本: 5.0.45-community-nt-log
Protocol version: 10
MySQL 字符集: UTF-8 Unicode (utf8)
MySQL 连接校对:utf8_general_ci
phpMyAdmin - 2.10.2
MySQL client version: 5.0.37
Language: 中文-Chinese simplified
其中，打开了数据库列表显示如下：
数据库 整理
mymy2012 utf8_general_ci
mysql utf8_general_ci
phpmyadmin utf8_bin
test utf8_general_ci
统计: 4 utf8_general_ci
新建php页面时中文显示正常，插入记录集导航条和记录集导航数据时的文字是英文，当运行预览（F12）时，IE页面出现的中文乱码，英文能正常显示；
当从php页面提交插入记录并返回页面时，显示的提交内容没有乱码，只是在Dreamweaver制作时写入的中文是乱码；
然后打开http://localhost/phpmyadmin/页面查看数据库，发现刚才输入的中文显示为乱码；
这个时候，我在数据库里修改刚才输入的中文并保存，这时数据库能显示的是中文，但回到在php页面运行预览（F12）时，在数据库里修改的那部分出现的是很多问号（?），其他没有修改的内容没有变化。请各位高手出手相助！该如何修改才不会乱码？

import java.io.UnsupportedEncodingException;
public class ToNewString {
public static String toNewS(String a){
String b=null;
try {
b= new String(a.getBytes("iso-8859-1"),"gb2312");
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return b;
}
}
上面就是将汉字a转换为gb2312的b，你可以直接调用String b="张三" String a=ToNewString.toNewS(b);

在里面写一句话：set names gbk;
