How to solve the Chinese garbled code read by PHP from MySQL?

Solution: 1. Use to set UTF-8 encoding in the web page file; 2. Set UTF-8 encoding when creating a new database; 3. When connecting to the database with PHP, use "mysql_query("set names 'utf8'");"Set the character set of the data to utf-8.

MySQL's support for Chinese is still very limited, especially for novices. Whenever there is a problem with garbled characters, it will be a headache.

Garbled code problem:

Using PHPmyAdmin to operate the MySQL database Chinese characters are displayed normally, but when using the PHP web page to display MySQL data, all Chinese characters become ?Number.

Symptoms: It is normal to input Chinese characters using PHPmyAdmin, but when the PHP web page displays MySQL data, the Chinese characters become ? signs, and there are as many ? signs as there are Chinese characters.

Reason: There is no code in the PHP web page to tell MySQL what character set to use to output Chinese characters.

Solution:

1. Set encoding for web page file head

<meta charset="UTF-8">

2. Use utf-8 encoding when saving PHP pages. You can use Notepad or convertz802 to convert the file

3. When creating a new database in MYSQL, select UTF-8 encoding for the database, and the character set is set to utf-8_unicode_ci (Unicode (multi-language), size-insensitive Write),

The collation of the table in the library is set to utf-8_general_ci

The collation of each field in the table is set to utf-8_general_ci

4. When connecting to the database in PHP, that is, add

//设置数据的字符集utf-8
mysql_query("set names 'utf8'");
mysql_query("set character_set_client=utf8");
mysql_query("set character_set_results=utf8");

after mysql_connect(). Note that it is utf8, not utf-8.

If your web page encoding is gb2312, that is SET NAMES GB2312. However, the editor strongly recommends that web page encoding, MySQL data table character set, and PHPmyAdmin all use UTF-8.

The above four points can achieve utf-8 encoding for the entire site, and there will be no Chinese garbled characters in the database.

Expansion:

Garbled code problem: An error occurred when entering data using PHPmyAdmin, and the input is not allowed or garbled codes appear

Solution Method: This is a setup issue. Please install the latest version of PHPmyAdmin or Appserv, open PHPmyAdmin, MySQL character set: UTF-8 Unicode (utf8); MySQL connection proofreading should be utf8_unicode_ci; when creating a new database, please also select utf8_unicode_ci in the finishing column.

It is also best to use utf-8 for the web page character set. UTF-8 is an international standard encoding and a trend.
