What should I do if Chinese characters in php cannot display Chinese properly?

When using PHP to write a Chinese website and display it, you may encounter the problem that Chinese characters cannot be displayed properly. This problem might bother you, but don’t worry because solving this problem is not complicated. In this article, we will teach you step by step how to solve this problem.

1. Confirm web page encoding

The most common reason is that the web page encoding is incorrect, resulting in Chinese characters not being displayed properly. Therefore, please confirm your page encoding first. In HTML documents, you can use the tag in the tag to set the web page encoding. For example:

This tag tells the browser that the web page uses UTF-8 encoding. If your page is not encoded correctly, you can try changing the encoding in this tag.

2. Confirm PHP file encoding

If your web page encoding has been set correctly, but Chinese characters still cannot be displayed normally, you need to confirm the PHP file encoding. PHP files use ISO-8859-1 encoding by default. This encoding method does not support Chinese characters. Therefore, you need to change the encoding of the PHP file to UTF-8 or other encoding that supports Chinese characters.

In text editors such as Notepad, you can change the encoding method through the "Format" menu. When writing in PHP, you can also add the following code at the beginning of the PHP file:

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

This line The code tells the browser that the web page uses UTF-8 encoding. If your PHP file is not encoded correctly, you can try changing the encoding or adding that line of code.

3. Confirm database encoding

If you are reading Chinese characters from the database and displaying them, you need to confirm the database encoding. PHP usually uses the MySQL database, which uses Latin1 encoding by default. Therefore, if your database contains Chinese characters, you need to change the database encoding to UTF-8 or other encoding that supports Chinese characters.

In the MySQL database, you can change the database encoding method through the following command:

ALTER DATABASE database_name CHARACTER SET utf8;

If your database encoding method is incorrect, you can try Change the encoding.

Summary

The failure of Chinese characters to display properly is a common problem when writing Chinese websites in PHP, but it is usually not difficult to solve. It should be noted that correct web page encoding, PHP file encoding and database encoding are all important. If you still can't solve the problem, you can try searching the Internet for other solutions or ask the developer for help.
