 New Comment:

Thanks for reporting. The current Windows API doesn't seem to provide a way to query these
record types. One can query an authority of a host, but not the autority record itself. Until
I've overseen something, there's no way to map this functionality currently :(

Thanks.

Description:
------------
Support for this record was added to dns_get_record in 7.0.16, but Windows uses a separate
implementation of dns_get_record (defined in dns_win32.c) that did not get updated.

The DNS_CAA constant is defined on Windows.

Original commit: https://github.com/php/php-src/commit/280e9cb28d07a69e56ebcde4c368f3053298abe3

Test script:
---------------
var_dump(dns_get_record('google.com', DNS_CAA));

Expected result:
----------------
array(1) {
  [0]=>
  array(7) {
    ["host"]=>
    string(10) "google.com"
    ["class"]=>
    string(2) "IN"
    ["ttl"]=>
    int(60)
    ["type"]=>
    string(3) "CAA"
    ["flags"]=>
    int(0)
    ["tag"]=>
    string(5) "issue"
    ["value"]=>
    string(8) "pki.goog"
  }
}

Actual result:
--------------
PHP Warning: dns_get_record(): Type '8192' not supported in php shell code on line 1
bool(false)
