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_encoding is 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).

The following is a simple example that demonstrates how to use the above function to convert a Chinese character string to UTF-8 encoding:

$chineseStr = "你好世界";
$utf8Str = chineseToUTF8($chineseStr);
echo $utf8Str; // 输出为 UTF-8 编码的字符串

By calling the chineseToUTF8 function, we You can convert the Chinese characters in $chineseStr to UTF-8 encoding and store the result in the $utf8Str variable. Finally, by echo output $utf8Str, you can see the converted UTF-8 encoded string.

It should be noted that when using this method to convert Chinese characters into UTF-8 encoding, ensure that the original encoding parameters are consistent with the actual situation to avoid garbled characters.

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.
