What are some potential pitfalls to be aware of when integrating a Whois query into a PHP website?

One potential pitfall when integrating a Whois query into a PHP website is handling errors and exceptions that may arise during the query process. It's important to properly handle these errors to prevent the website from crashing or displaying sensitive information. One way to address this is by using try-catch blocks to catch any exceptions thrown during the Whois query and handle them appropriately. 

try {
    $domain = 'example.com';
    $whois = new Whois($domain);
    $result = $whois->lookup();
    
    // Process the Whois query result
    echo $result;
} catch (Exception $e) {
    // Handle any exceptions thrown during the Whois query
    echo 'An error occurred: ' . $e->getMessage();
}
