How can the separation of PHP and JavaScript code be optimized for better performance when using Fancybox?

To optimize the separation of PHP and JavaScript code for better performance when using Fancybox, it's best to keep the PHP code separate from the JavaScript code by using AJAX to load content dynamically. This way, the PHP code can handle the backend logic and data processing, while the JavaScript code can handle the frontend presentation and interactions. By separating the two, it allows for cleaner code organization and better performance. 

// PHP code to handle AJAX request for fetching data
add_action('wp_ajax_my_fancybox_content', 'my_fancybox_content');
add_action('wp_ajax_nopriv_my_fancybox_content', 'my_fancybox_content');

function my_fancybox_content() {
    // Process data or query database to fetch content
    $content = '<div>Your fancybox content here</div>';

    // Return the content as JSON response
    wp_send_json_success($content);
}
