How can the performance of highlighting PHP code be improved in a forum setting?

The performance of highlighting PHP code in a forum setting can be improved by using a lightweight syntax highlighter library like Prism.js. This library efficiently highlights code on the client-side without putting too much strain on the server. By implementing this solution, forum users can enjoy fast and responsive code highlighting without experiencing any lag. ```html <!-- Include Prism.js library --> <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/prismjs@1.25.0/themes/prism.min.css"> <script src="https://cdn.jsdelivr.net/npm/prismjs@1.25.0/prism.min.js"></script> <!-- Add 'language-php' class to PHP code blocks for highlighting --> <pre><code class="language-php"> <?php // Your PHP code here ?> </code></pre> ```
