How can one ensure proper HTML sanitization and formatting when processing form data in PHP?

To ensure proper HTML sanitization and formatting when processing form data in PHP, you can use the `htmlspecialchars()` function to convert special characters to HTML entities. This helps prevent XSS attacks by escaping potentially harmful input. Additionally, you can use CSS for formatting instead of inline styles to maintain separation of content and presentation. 

// Process form data
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = htmlspecialchars($_POST['name']);
    $email = htmlspecialchars($_POST['email']);
    
    // Further processing or validation of the sanitized data
}
