What are common pitfalls when working with WhoIs data in PHP scripts?

One common pitfall when working with WhoIs data in PHP scripts is not properly handling errors or exceptions that may occur during the data retrieval process. To solve this issue, it is important to implement error handling mechanisms such as try-catch blocks to catch any potential errors and handle them appropriately. 

try {
    $whoisData = file_get_contents('http://example.com/whois');
    // Process the WhoIs data here
} catch (Exception $e) {
    echo 'Error retrieving WhoIs data: ' . $e->getMessage();
}
