Are there any best practices for using PHP to gather information about DNS servers?

To gather information about DNS servers using PHP, one best practice is to use the `dns_get_record()` function, which retrieves various types of DNS records for a specified domain. This function can be used to query DNS servers for information like A, MX, TXT, and NS records. By utilizing this function, you can easily gather and display DNS information in your PHP application. 

$domain = 'example.com';
$dns_records = dns_get_record($domain, DNS_ALL);

foreach ($dns_records as $record) {
    echo "Type: " . $record['type'] . "<br>";
    echo "Host: " . $record['host'] . "<br>";
    echo "IP: " . $record['ip'] . "<br>";
    echo "TTL: " . $record['ttl'] . "<br>";
    echo "<br>";
}
