Reasons and solutions for Chinese characters displaying garbled characters in PHP

In the process of using PHP for development, sometimes we encounter the problem of Chinese characters displaying garbled characters. Chinese characters are the main form of expression of Chinese. If Chinese characters cannot be displayed correctly, it will affect the aesthetics and readability of the website. This article will introduce some common causes and solutions, hoping to help you solve this problem.

1. Inconsistent character encoding

One of the main reasons why Chinese characters display garbled characters is that character encoding is inconsistent. In website development, common character encodings include GBK, UTF-8, Big5, etc. If the encoding of the read or output content is inconsistent with the encoding set by the page, garbled characters will appear.

For example, if the content stored in the database is GBK encoded, but the page is set to UTF-8 encoding, garbled characters will appear. The way to solve this problem is to set their encoding to be consistent.

2. The font is missing or not supported

Another common reason is that the font is missing or not supported. When developing websites, we often use CSS to style fonts. If the font file does not exist or does not support Chinese characters, garbled characters will result.

The solution to this problem is to use a font that supports Chinese characters or load the corresponding font file. For example, when setting the font style in CSS, you can set it to:

font-family: "Microsoft YaHei", "微软雅黑", Arial, sans-serif;

This way, fonts that support Chinese fonts can be used first for display, avoiding the problem of garbled characters.

3. The output encoding setting is incorrect

When outputting Chinese characters in PHP, the correct output encoding needs to be set. Normally, we use the header() function to set the output encoding:

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

This function needs to be called before outputting anything. It tells the browser to use utf-8 encoding to parse the page, thereby ensuring that the page can display Chinese characters correctly.

4. Other issues

The reasons for garbled Chinese characters also include other aspects, such as file encoding, server configuration, etc. When encountering the problem of garbled Chinese characters, you need to carefully investigate the cause, analyze the problems one by one and solve them.

Summary

The display of garbled Chinese characters is a common problem in the website development process, but it is also a relatively easy problem to solve. Usually, you only need to pay attention to the above aspects to successfully solve the problem. I hope this article can help you better solve the problem of garbled Chinese characters.
