完美解决mysql下utf 8的乱码问题

完美解决mysql下utf-8的乱码问题
建表时先加上default charset=utf8;
插入中文数据之前(Mysql命令提示符下)是用set names gb2312;
在php页面中设置是mysql_query('SET NAMES UTF8');
在php页面(已设定为utf8后)中插入中文数据不会出现乱码,应该插入数据库的时候就是以utf8字符集插入中文数据的故不会出现问题!
在php页面前面不要忘了加上header('content-type;text/html;charset=utf-8');
大家在MySQL命令提示符下想查看数据,中文数据有可能是如下 '?????'
所以大家想查看到正确的中文要与插入中文数据一样使用set names gb2312;
例子:
CREATE DATABASE mydb;
USE mydb5;
CREATE TABLE news
(
      news_id int not null auto_increment,
      news_title varchar(100) not null,
      news_contents text not null,
      news_date datetime not null,
      primary key(news_id)
)default charset=utf8;
set names gb2312;  
INSERT INTO news VALUES(null, '新闻1', '111111', now());
INSERT INTO news VALUES(null, '新闻2', '222222', now());
INSERT INTO news VALUES(null, '新闻3', '333333', now());
INSERT INTO news VALUES(null, '新闻4', '444444', now());
INSERT INTO news VALUES(null, '新闻5', '555555', now());
