检查域是否有记录 CNAME 并指向我的服务器

Question

I need to check if my users have add correctly the CNAME record but with this code I get empty array

<?php

$domain="martinashop.club";
if(checkdnsrr($domain,"CNAME")) {
  echo "Passed";
} else {
  echo "Failed";
}
echo "<br>";

print_r(dns_get_record($domain,DNS_CNAME));
echo "<br>";
print_r(dns_check_record($domain,"CNAME"));
?>

I not understan why not get the RECORD my domain using Clouflare maybe this get a error?

You can't have a CNAME on a naked domain.

CNAMEs can only exist as single records and not combined with any other resource records. Since a domain always has a SOA and NS record, you cannot use a CNAME for the domain. This is specified in RFC 1034 , section 3.6.2.
