本人初学php+mysql，安装了XAMPP for windows 1.7.3。写了一个简单页面（用的是mysqli_connect()和mysqli_query()）向数据库里面写入信息，但是在phpMyAdmin里面显示成乱码，在MySQL命令行里面显示也是乱码。但是在我自己做的php页面从数据库里面读取同样的数据，却能够正常显示内容。字符集都改成了UTF-8。数据库的字符集是utf8-unicode_ci。请问这是怎么回事？谢谢！
调试欢乐多
MySQL 中文显示乱码
mysql_client_encoding($Code)
(PHP 4 >= 4.3.0, PHP 5)mysql_client_encoding -- 返回字符集的名称
说明
int mysql_client_encoding ( [resource link_identifier] )
mysql_client_encoding() 返回当前连接的默认字符集名称。 例子 1. mysql_client_encoding() 例子<?php
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
$charset = mysql_client_encoding($link);
printf ("current character set is %s\n", $charset);
?> 以上例子将产生如下输出： current character set is latin1

I couldn't get any luck with all the stuff mentioned below, and despite having an unicode DB, and setting all my field to utf8_general_ci...
After looking around, I found that this page: http://dev.mysql.com/tech-resources/articles/4.1/unicode.html was adding the fields with an extra info before each value:<?
mysql_query("INSERT INTO table SET field = _utf8'value'");
?>
Mind the "_utf8" before the field value, and outside of the quotes.This works for me wether in an Insert or an Update statement.No need here for a <? mysql_query("SET NAMES utf8"); ?> before each query, or to change anything in the config files (that was important since I don't have access to these).

The right lines to put in /etc/my.cnf (or other MySQL options file) are:[client]
init-command="SET NAMES utf8"Unfortuantely the PHP mysql_connect() function does not use MySQL options files so this is not a sollution for changing the default connection character set for mysqlclient library v4.1+.The only working sollution remains:mysql_query("SET NAMES utf8", $conn);(of course /ext/mysql/php_mysql.c can always be patched ;] )

If you set the encoding in my.cnf like[mysqld]
init_connect='SET NAMES utf8'note that the content of init_connect is not executed for users that have the SUPER privilege - ie root!

I have had problems with encoding after export of tables (from hosting - via PhpMyAdmin) and import them to other machine (my notebook - via PhpMyAdmin too). In PhpMyAdmin the encoding of all data was shown correctly, not that good with the web pages (data pulled via php).
The first point is indication, that the data was imported correctly, but php script has got other character set than MySql is sending.The script's character set is set in header: <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-2">. MySql setting was latin1.Then following code helped me:<?php
mysql_query("SET CHARACTER SET 'latin2'", $conn);
?>

Notice the difference between following two SQL statements:SET NAMES 'charset_name'
SET CHARACTER SET charset_nameFor more detail see

the above (as it seems to be vaguely indicated in the mysql manual) works only with mysql 4.1+

If you experience weird problems, like some UTF-8 characters (the Unicode character č and a few others in my case) seemingly being changed to garbage by mysql_query, you may need to do something like this before your actual query:<?php
mysql_query("SET NAMES 'utf8'", $conn);
?>Took me days to figure that one out...
在 mysql_connect()成功之后，执行以下这句试试:mysql_query("SET NAMES 'GB2312'");.
我是这么解决问题的。
MySQL里的数据库、表以及表的字段都是可以设置字符集的，在MySQL理看到的是乱码，而在程序里看到的是正常的，说明你在建表的时侯，字符集定义的跟程序里的不一样，这得修改表以及表字段的字符集设置，这样以后加的数据就能正常显示了，但之前的数据在数据库里看还可能是乱码。
相关设置你Google下，应该都有的，我以前遇到过这类问题，都是这么解决的。仅仅是个人的一点建议，希望能帮到你，不过又有点担心会误导你，呵呵，祝你好运！
