A brief analysis of 3 methods of converting Chinese characters into UTF-8 encoding in PHP

PHP is a server-side scripting language that is widely used in website development. However, when using PHP to process Chinese data, it is sometimes necessary to convert Chinese characters into UTF-8 encoding. This article will introduce the method of converting Chinese characters to UTF-8 encoding in PHP.

Why do we need to convert Chinese characters into UTF-8 encoding?

When using PHP to process Chinese data, UTF-8 encoding format needs to be used in many cases. This is because UTF-8 encoding is an encoding that supports languages ​​around the world and can represent almost all characters in the world. Moreover, UTF-8 encoding can also solve problems such as Chinese garbled characters.

How to convert Chinese characters into UTF-8 encoding in PHP

Method 1: Use the iconv function

PHP provides a built-in function iconv that can convert a string from one character set to another. This function can be used when converting Chinese characters to UTF-8 encoding.

Sample code:

$gbk_str = "中文";
$utf8_str = iconv("gbk","utf-8",$gbk_str);
echo $utf8_str;

Run result:

中文

In this example, $gbk_str is a string, and its encoding method is GB2312. Now it needs to be converted to UTF-8 encoding. Here we will use the iconv function. The method of use is to use the original encoding method gbk as the first parameter, the string to be converted as the second parameter, and finally specify the target encoding method utf-8.

Method 2: Use the mb_convert_encoding function

The mb_convert_encoding function is another function in PHP used for character set conversion. Its usage is similar to iconv, and it can also successfully convert Chinese characters to UTF-8 encoding.

Sample code:

$gbk_str = "中文";
$utf8_str = mb_convert_encoding($gbk_str,"UTF-8","GB2312");
echo $utf8_str;

Run result:

中文

In this example, the original encoding method GB2312 is passed to the mb_convert_encoding function as the third parameter, and finally we get A UTF-8 encoded string.

Summary

In this article, we introduced two methods of converting Chinese characters to UTF-8 encoding in PHP. No matter which method you choose, it can help you effectively solve the problem of processing Chinese data in PHP development. It is worth noting that it is crucial for character set conversion to ensure that the encoding of the source string is accurate.
