DNSCheckValidation line 202 code error

[philoooooo]

Hello,
On line 202 ->
if (empty($dnsRecord['target']) || $dnsRecord['target'] === '.') {

if record target = 0, empty ->true.

Wouldn't it be better with :
if ((array_key_exists('target',$dnsRecord) && $dnsRecord['target'] == null) || $dnsRecord['target'] === '.') {

?

Thanks
Phil

Hey @philoooooo
Happy to merge a PR with the updated code, including a test for this case.
