Chinese display garbled problem

When we access the MySQL database through PHP in the way we used to, even if we set the default character set of the table to UTF8 and send the query via UTF-8 encoding, you will find that the database is still garbled.

In fact, the simple way is to set by phpMyAdmin.

Set the following:

1: Language set to Chinese (zh-utf-8)

2:mysql Character Set: UTF-8 Unicode (UTF8)

3:mysql Connection Proofing: Utf8_general_ci

4: When the new database and datasheet, the collation of the selection utf8_general_ci

Through the above settings, in the phpMyAdmin operation and query, the Chinese characters are not garbled.

But you will find that in the PHP program with the previous SQL statements query results or garbled, the problem is on the connection connection layer.

The workaround is to send a query statement after the database is successfully connected:

The code is as follows

1: $this->linkid = mysql_connect ($this->host, $this->user, $this->password);
2:mysql_query (' SET NAMES ' UTF8 ', $this->linkid);
Or:

DEFINE (' LINK ', mysql_connect (Db_host, Db_user, Db_password));
mysql_query ("SET NAMES ' UTF8 '", LINK);

GBK encoded.

The code is as follows

$mysql _mylink = mysql_connect ($mysql _host, $mysql _user, $mysql _pass);
mysql_query ("SET NAMES ' GBK '");
