Analysis and solution to the problem of garbled Chinese names in PHP

In the process of PHP development, we often encounter the problem of garbled Chinese names. This is because of Chinese character encoding and transmission caused by inconsistencies. This article will analyze the causes of the problem of garbled Chinese names and provide some solutions, with specific code examples for reference.

Problem analysis:

1. Inconsistent character encoding: In PHP, the encoding of the string needs to be consistent with the encoding of the page, the encoding of the database, etc., otherwise There will be garbled code problems.
2. The browser encoding is inconsistent with the page encoding: If the encoding declared by the web page is inconsistent with the encoding actually displayed, it will also cause the problem of garbled Chinese names.
3. Database encoding setting error: If the encoding setting of the database is incorrect, garbled characters will appear when inserting and reading Chinese characters.

Solution:

1. Set PHP file encoding: Add the following code to the header of the PHP file and declare that the file encoding is UTF- 8:

   header('Content-Type: text/html; charset=utf-8');

2. ##Set HTML page encoding: Add the following code to the head of the HTML page to declare that the page encoding is UTF-8:

3. Set encoding when connecting to the database: When connecting to the database, set the encoding of the database to UTF-8:

   mysqli_set_charset($connection, 'UTF8');

4. Specify the encoding of the database table: When creating the database table, set the default encoding of the table to UTF-8:

   CREATE TABLE users ( name VARCHAR(50) CHARACTER SET utf8 );

Code example:

"; } mysqli_close($connection); ?>

The above is the analysis and solution to the problem of garbled Chinese names in PHP, and provides specific code references. By correctly setting the character encoding, page encoding, and database encoding, the problem of garbled Chinese names can be effectively solved and Chinese characters can be displayed normally. Hope this article is helpful to you.
