Are there any potential pitfalls or common mistakes to avoid when using checkdnsrr in PHP?

One potential pitfall when using checkdnsrr in PHP is not properly handling errors or exceptions that may occur during the DNS lookup process. To avoid this, it's important to wrap the checkdnsrr function call in a try-catch block to catch any potential exceptions and handle them accordingly. 

try {
    if(checkdnsrr('example.com', 'A')) {
        echo 'DNS record found for domain';
    } else {
        echo 'No DNS record found for domain';
    }
} catch (Exception $e) {
    echo 'Error: ' . $e->getMessage();
}
