What are some best practices for handling and processing HTML shortcodes in PHP to ensure accurate data extraction and display on the frontend?

When handling HTML shortcodes in PHP, it is crucial to properly sanitize and validate the input data to prevent security vulnerabilities such as XSS attacks. Additionally, using a reliable HTML parser library can help accurately extract and process the shortcode content for display on the frontend. 

// Example of handling and processing HTML shortcodes in PHP

// Sample HTML content with shortcode
$html_content = '<div>Lorem ipsum [shortcode] dolor sit amet</div>';

// Regular expression to match shortcode pattern
$shortcode_pattern = '/\[shortcode\]/';

// Extract shortcode content using preg_match
if (preg_match($shortcode_pattern, $html_content, $matches)) {
    $shortcode_content = 'Shortcode found';
} else {
    $shortcode_content = 'Shortcode not found';
}

// Display processed content
echo $shortcode_content;
