------------
When trying to resolv the ip address of a hostname given in /etc/hosts,
it's works fine, but does not work when trying to resolv via the DNS
server though.

Reproduce code:
---------------
var_dump(dns_get_record("xxx.xxx.com"));
var_dump(fsockopen("xxx.xxx.com", 80, $error, $errstr));
Expected result:
----------------
array(1) {
[0]=>
array(5) {
["host"]=>
string(12) "xxx.xxx.com"
["type"]=>
string(1) "A"
["ip"]=>
string(13) "192.168.200.6"
["class"]=>
string(2) "IN"
["ttl"]=>
int(86400)
}
}
resource(20) of type (stream)
Actual result:
--------------
array(1) {
[0]=>
array(5) {
["host"]=>
string(12) "xxx.xxx.com"
["type"]=>
string(1) "A"
["ip"]=>
string(13) "192.168.200.6"
["class"]=>
string(2) "IN"
["ttl"]=>
int(86400)
