The problem of using UTF-8 encoding for MYSQL database

1. Use phpmyadmin to create the database and data table

Create the database When creating a data table, please set "Organization" to: "utf8_general_ci" or execute the statement:

CREATE DATABASE `dbname` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

When creating a data table: If the field stores Chinese, you need to set "Organization" to: " utf8_general_ci",

If this field stores English or numbers, the default is fine.

Corresponding SQL statement, for example:

CREATE TABLE `test` ( 
`id` INT NOT NULL , 
`name` VARCHAR( 10 ) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL , 
PRIMARY KEY ( `id` ) 
) ENGINE = MYISAM ;

2. Use PHP to read and write the database

After connecting to the database:

$connection = mysql_connect($host_name, $host_user, $host_pass);

Add two lines:

mysql_query("set character set 'utf8'");//读库 
mysql_query("set names 'utf8'");//写库 
//其实读写都可以只加入
mysql_query("set names 'utf8'");

Then you can read and write the MYSQL database normally.

The environment made using appserv-win32-2.5.10 uses the default utf8 encoding when installing this package.

When writing the database connection file, write:

$conn = mysql_connect("$host","$user","$password"); 
mysql_query("SET NAMES 'UTF8'"); 
mysql_select_db("$database",$conn);

Then when making the page, pay attention to this sentence:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

In this way, regardless of the Chinese input into the database, or the page display, It's all normal.

In the DW CS4 version, the utf8 page is also generated by default.

Similarly, if you first write the database connection file as: mysql_query("SET NAMES 'GBK'");

Then the page will also change accordingly:

<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
