How to convert PHP Chinese characters to UTF-8 encoding

PHP is a commonly used server-side scripting language commonly used for web development. When processing Chinese text, we often encounter situations where we need to convert Chinese characters to UTF-8 encoding. This article will introduce how to use PHP to convert Chinese characters into UTF-8 encoding, and give specific code examples.

Generally speaking, the default encoding method of PHP is UTF-8, but sometimes we need to manually convert Chinese characters to UTF-8 encoding to ensure that the text can be displayed correctly on different platforms.

The following is a simple PHP function that can convert Chinese characters to UTF-8 encoding:

function chineseToUTF8($str) { return mb_convert_encoding($str, 'UTF-8', 'GBK'); }

In this function,mb_convert_encodingis used in PHP For the function that performs encoding conversion, the first parameter is the string to be converted, the second parameter is the target encoding (here is UTF-8), and the third parameter is the original encoding (here is GBK, it can also be based on the actual situation Revise).

I hope that through this article, readers will have a clearer understanding of how to convert Chinese characters into UTF-8 encoding in PHP and be able to apply it in their own projects.
