What's wrong with php encoding not being able to display Chinese?

With the development of the Internet, websites have become an indispensable part of our daily lives. The implementation of the website requires a variety of programming languages, among which PHP is a commonly used programming language. However, if you find that Chinese cannot be displayed properly when writing a website in PHP, then you need to know how to solve this problem.

There are many reasons why the encoding cannot be displayed normally. The most common reason is that the encoding format is incompatible. When you use PHP to write a website, different file types may use different encoding formats, which requires us to make corresponding adjustments. Here are some common solutions:

1. Set the default encoding format

When using PHP to write a website, we need to set the encoding format of the file to UTF-8. Because UTF-8 is an encoding format that supports all characters and is compatible with text in multiple languages. In order to ensure that the encoding format of the file is correct, we can add the following code at the beginning of the PHP file:

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

This code can set the encoding format of the web page to UTF-8, thereby ensuring the normal display of Chinese characters.

2. Convert encoding format

If you find that Chinese characters are garbled or cannot be displayed properly when writing a PHP program, it may be because the encoding format of the PHP file is different from the actual encoding format of the website. You can convert the encoding format to UTF-8 by doing the following:

Use a text editor to open the PHP file you want to process and select the "Save As" option. When saving the file, select UTF-8 encoding format and select "Overwrite original file".

3. Use the mb_convert_encoding() function

If you still cannot solve the problem that the Chinese encoding cannot be displayed, you can use PHP's mb_convert_encoding() function to convert characters from one encoding to another encoding. . This function can convert some common encoding formats (such as GBK, GB2312, etc.) into UTF-8 encoding, thereby solving the problem that Chinese encoding cannot be displayed normally.

Sample code:

$string = '中文字符串';
echo mb_convert_encoding($string, 'UTF-8', 'GBK');

This code can convert GBK-encoded Chinese strings to UTF-8 encoding, thereby achieving normal display of Chinese characters.

In short, when using PHP to write a website, the problem of Chinese characters not being displayed properly may often occur, but as long as you follow the above methods, the problem will be solved quickly.
