What are some best practices for highlighting syntax and line numbering in PHP code?

To highlight syntax and add line numbering to PHP code, you can use a code highlighting library like Prism.js or highlight.js. These libraries provide easy-to-use syntax highlighting features and support line numbering for code blocks. By including the necessary CSS and JavaScript files in your project, you can easily apply syntax highlighting and line numbering to your PHP code snippets. ```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 line-numbers"> <?php // Your PHP code here ?> </code></pre> <script src="https://cdn.jsdelivr.net/npm/prismjs/prism.js"></script> <script src="https://cdn.jsdelivr.net/npm/prismjs/plugins/line-numbers/prism-line-numbers.js"></script> </body> </html> ```
