The field value written by PHP is garbled

1. Use phpmyadmin to create the database and data table

When creating the database, 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 the 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

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

Join:

mysqli_query("set character set 'utf8'");//读库

mysqli_query("set names 'utf8'");//写库

You can read and write the MYSQL database normally.

The environment used is appserv-win32-2.5.10. When installing this package, the default utf8 encoding is used.

When writing the database connection file, write:

$conn = mysqli_connect("$host","$user","$password");

mysqli_query("SET NAMES 'UTF8'");

mysqli_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, everything will be normal.

In the DW CS4 version, the utf8 page is generated by default. Similarly, if you first write the database connection file, you write:

mysqli_query("SET NAMES 'GBK'");

The page should also change accordingly:

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