How to set Chinese font in php

With the popularity of Chinese on the Internet, more and more websites use Chinese as part of their website content. However, in some cases, Chinese characters may not display and render properly. This situation is usually caused by font settings in the PHP configuration file. In this article, we will discuss how to properly set up Chinese fonts in PHP.

What is a font?

In the computer field, font refers to the visible form of a set of characters, including font size, font type, font color, font style, etc. Chinese fonts will affect the appearance and rendering of Chinese characters we see on web pages or documents. Therefore, it is very important to choose and set the right font.

Font Settings for PHP

PHP is a popular server-side programming language used to create dynamic web pages, web applications, and websites. If the font settings in the PHP configuration file are incorrect, Chinese characters will not be displayed properly.

Install font files

To set Chinese fonts for PHP, you first need to ensure that the corresponding font files are installed in the system. If you need to use local font files, you can install the font directly on the operating system. If you need to use a third-party font, you can download and install the corresponding font file from its official website.

Modify the PHP configuration file

Modify the font settings in the PHP configuration file to ensure that PHP can correctly obtain and render Chinese characters. To modify the PHP configuration file, you can use the following methods:

1. Open the php.ini file

sudo nano /etc/php/7.4/apache2/php.ini

2. Search for the following lines:

;extension=gd

3. Uncomment the following lines according to the actual situation:

;extension=gd.so

4. Add the following code at the end of the file:

[gd]
; Tell the jpeg decode to ignore warnings and try to create
; a gd image. The warning will then be displayed as notices
warning-pixels = 0
gd.jpeg_ignore_warning = 1

; Tell gd to use TrueType fonts
gd.ttf_supported = 1

; Use any Chinese TrueType font, you should change the path
; according to your own environment
ttfontpath = "/usr/share/fonts/truetype/microsoft-fonts/simhei.ttf"

; Set the default font for text functions
default_font = simhei

5. Save and close the file.
6. Restart Apache for the new configuration to take effect.

sudo service apache2 restart

Now, PHP has correctly set up the Chinese font and can render Chinese characters correctly.
