PHP character encoding problem causes Chinese names to display abnormally

PHP character encoding problem causes Chinese names to display abnormally, requiring specific code examples

Recently, in the process of developing a website, I encountered a confusing problem : An exception occurred when displaying Chinese names on the web page. After investigation, it was found that this was caused by a PHP character encoding problem. In this article, I will explain this problem in detail and provide specific code examples to solve this problem.

Problem Description

On the website, users can submit Chinese names through the form, and these names will be displayed on the page. However, when a user submits a name that contains Chinese characters, the Chinese name displayed on the page has garbled characters or garbled symbols instead of the correct Chinese characters. This brings troubles to the user experience and also affects the overall image of the website.

Problem Analysis

After investigation, it was found that this problem was caused by incorrect character encoding settings in the PHP file. PHP's default character encoding is ISO-8859-1, and the Chinese characters we need to process belong to UTF-8 encoding. Therefore, when outputting Chinese characters, the characters need to be correctly encoded and converted to ensure that they can be displayed correctly on the web page.

Solution

The following is a simple sample code that demonstrates how to deal with PHP character encoding issues to ensure that Chinese names can be displayed correctly on web pages:

<? php
//Set the page encoding to UTF-8
header('Content-Type: text/html; charset=utf-8');

//Receive the Chinese name submitted by the user
$name = $_POST['name'];

// Convert Chinese names to UTF-8 encoding
$name = mb_convert_encoding($name, 'UTF-8', 'auto');

// Output Chinese name
echo 'Your Chinese name is:' . $name;
?>

In this code, the encoding of the page is first set to UTF-8 through the header function to ensure that the page can correctly display Chinese characters. Then use the mb_convert_encoding function to convert the Chinese name submitted by the user into UTF-8 encoding to ensure that it is displayed correctly on the page.

Conclusion

By correctly setting the character encoding of the PHP file and performing correct encoding conversion of the Chinese characters that need to be processed, the problem of abnormal Chinese name display can be solved. When developing a PHP website, it is important to pay attention to the character encoding settings of the file to ensure that the Chinese data submitted by users can be displayed correctly on the web page, thereby improving the user experience of the website.
