Efficient compression of web fonts: a clever combination of PHP and font subsetting

Webfont can significantly improve web page loading speed and user experience, but the complete Chinese webfont is huge. In order to optimize web page performance, we need to subset Chinese fonts and only retain the actual glyphs used by the page. This article discusses how to use PHP to achieve this goal efficiently.

Although JavaScript (such as font-spider, fontmin) and Python (such as Fontforge) have provided font subsetting solutions, is PHP competent?

Using the PHP function library directly cannot directly handle font subsetting. PHP is mainly responsible for backend logic and is not an ideal tool for handling font file formats. To realize subsetting of fonts in PHP environment, external tools are required, which are responsible for process control and interaction with external tools, such as calling command line tools or subsetting programs written in other languages.

Therefore, the best solution is not a pure PHP code implementation, but a combination of tools that are good at handling fonts, such as Python's Fontforge. PHP acts as a bridge, calls Fontforge for subsetting, and manages the entire process. This can not only take advantage of PHP, but also effectively complete font compression.
