关于PHP操作MYSQL数据库,乱码的问题,高手达人们,看看帮忙解决一下
我的情况如下:
我的网页是GB2312编码的,我的数据库的编码是UTF8的,如果我想让数据库里的内容读到网页上,要加上mysql_query("set names gb2312") 这句话,可以解决乱码的问题,这样显示在网页上的就不是乱码了.
但是当我在网页中加入一条插入数据库内容的语句,如果我不加mysql_query("set names gb2312")这句话,他插入数据库的内容是乱码,因为数据库的编码是UTF8,网页中的内容是GB2312编码,所以他显示乱码
但是我加上mysql_query("set names gb2312")这句话后,加入数据库的内容就不会显示乱码
我不明白的是mysql_query("set names gb2312")这句话,可以解决插入到UTF8数据库解决汉字乱码的问题?
mysql_query("set names gb2312")这句话不是设置字符集为GB2312吗?为什么插入UTF8数据库里不会乱码?相反我不加这句话就会显示乱码呢?
高手们帮帮小弟吧
------解决方案--------------------
set names 是用来设置客户端的字符集，与服务端没关系，
set names gb2312 等于是插入之前告诉数据库我是以gb2312的编码进来的，数据库根据进来时的编码来处理它，如果不加这句，数据库就不知道它是以什么编码进来的，这样就出现乱码了
同样道理 查询的时候，用set names gb2312 告诉数据库，我想得到gb2312编码的数据，你给我返回gb2312编码数据吧，数据库就给出gb2312的数据了，如果不加，给出的就是utf-8，显示到网页上就成乱码了
