Bug description:dns_get_record does not return false on dns server failure
Description:
------------
dns_get_record does not return false on dns server failure
If you make an example dns failure by changing resolv.conf to some silly ip
(i
used 1.3.3.7)
Requests for existing domain names: OK (array with stuff)
Requests for unexisting domain names: OK (empty array)
Requests for any domain when dns server does not respond: FAIL (empty
array)
Which makes it impossible to see if the dns server failed or if the domain
doesn't exist.
Documentation states: "This function returns an array of associative
arrays, or
FALSE on failure."
When the DNS server fails, that's considered a failure, correct?
Test script:
---------------
<?php
// try various domains with dns working/not working
print_r(dns_get_record('google.com', DNS_A));
?>
Expected result:
----------------
if dns does not respond within timeout, return false.
