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());
