Are there any pre-built classes or functions available for highlighting PHP code in a webpage?

To highlight PHP code in a webpage, you can utilize pre-built libraries or functions such as Prism.js or highlight.js. These libraries allow you to easily add syntax highlighting to your PHP code snippets on a webpage. By including the necessary CSS and JavaScript files from these libraries, you can achieve syntax highlighting for PHP code with minimal effort.
