[regression] dns_get_record does not return false on dns server failure

When doing a nslookup for this domain: the response is:

;; Got SERVFAIL reply from, trying next server

** server can't find NXDOMAIN

This worked on PHP version 5.5x, but when I upgraded to 5.6.26 this error occurred. The same error occurs on the production server, which is a different machine with a different OS, but same PHP version.

This is a regression from bug: #53092  ( ) . It was closed in 2014.

Test script:
$url = "";
$result = dns_get_record($url);

Expected result:
return empty array

Actual result:
throws "Warning: dns_get_record(): A temporary server error occurred. in ..."
and returns nothing (no array)

This error is due to the fact that the default value for the $type argument is DNS_ANY, which is ignored by most DNS servers.

dns_get_record('') doesn't work, but dns_get_record('', DNS_A) does.

Okay, changing to doc bug then.  Thanks!

We ran into this when querying for 'DNS_A', 'DNS_AAAA' or 'DNS_CNAME' records.

Code in question is here:

It looks like this is independent of the type - just that 'DNS_ANY' requests are mor likely to cause a server failure.

However even with a server failure there should be a way to handle the situation - either by returning false or by throwing a well defined error that can be caught.
