Why can't php display Chinese?

The reasons why php cannot display Chinese: 1. Encoding problems, reflected in character set mismatch and character encoding conversion problems; 2. Font problems, reflected in the lack of Chinese font support; 3. Environment configuration problems, reflected in The PHP operating environment does not support Chinese characters and server file encoding issues.

PHP, as a programming language widely used in web development, does have some problems in processing Chinese characters. Many beginners often encounter the problem that Chinese characters cannot be displayed properly when using PHP to develop Chinese websites. This article will delve into why PHP cannot display Chinese and provide some solutions.

1. Encoding issues

1. Character set mismatch

PHP needs to pay attention to the matching of character sets when processing Chinese characters. If UTF-8 encoding is used in the PHP file, and the character set used by the web server and database is other, such as GB2312 or GBK, Chinese characters will not be displayed normally. Therefore, it is important to ensure that the character set of all components is consistent.

Solution: Set the character set of all components to UTF-8. You can add header("Content-type:text/html;charset=utf-8"); at the beginning of the PHP file. Set the character set of the web page, or set default_charset to utf-8 in the PHP configuration file php.ini.

2. Character encoding conversion problem

PHP may encounter character encoding conversion problems when processing Chinese characters. For example, when reading Chinese data from a database, if the character set of the database and the character set of the PHP file are different, character encoding conversion is required. Otherwise, Chinese characters may be corrupted or displayed as garbled characters.

Solution: You can use PHP's built-in iconv function or mb_convert_encoding function for character encoding conversion. You need to choose the appropriate function to use according to the specific situation.

2. Font issues

1. Lack of Chinese font support

When PHP renders Chinese characters on a web page, it needs to be based on the browser’s Font configuration to select appropriate fonts for display. If the server where PHP is located lacks suitable Chinese font support, Chinese characters will not be displayed properly.

Solution: Install a suitable Chinese font on the server, and configure PHP to match the font path of the server.

3. Environment configuration issues

1. The PHP operating environment does not support Chinese characters

The default PHP operating environment of some servers does not enable Chinese characters Therefore, when using PHP to process Chinese characters, garbled characters may appear or cannot be displayed.

Solution: You can enable support for Chinese characters by modifying the php.ini configuration file.

2. Server file encoding issues

The server's file encoding settings may also affect whether PHP can correctly display Chinese characters. If the server file encoding is ANSI instead of UTF-8, Chinese characters may display abnormally.

Solution: Set the server file encoding to UTF-8 to ensure it is consistent with the PHP file.

Conclusion:

Although PHP has some problems in processing Chinese characters, through correct configuration and processing, the normal display of Chinese characters can be achieved. It should be noted that the character sets of all components must be consistent, use appropriate encoding conversion functions for character encoding conversion, provide suitable Chinese font support, and correctly configure the PHP running environment and server file encoding. Only in this way can we ensure that PHP can display Chinese characters correctly and provide users with a good browsing experience.
