What are the best practices for displaying and highlighting PHP code in a user-friendly manner on a website?

When displaying PHP code on a website, it is important to format and highlight the code in a user-friendly manner to make it easier for users to read and understand. One way to achieve this is by using syntax highlighting libraries such as Prism.js or highlight.js. These libraries will automatically detect and highlight PHP code, making it stand out from the rest of the content on the website. ```html <!DOCTYPE html> <html> <head> <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/prismjs/themes/prism.css"> </head> <body> <pre><code class="language-php"> <?php // Your PHP code here echo "Hello, World!"; ?> </code></pre> <script src="https://cdn.jsdelivr.net/npm/prismjs/prism.min.js"></script> </body> </html> ```
