Not sure,
I tried something locally and this is what i came up with (and what i think
expected behaviour could be)
<?php
echo "IPv6 preferred host (no A record, but CNAME to A):\n";
var_dump(gethostbyname("ipv6.google.com"));
echo "\nIPv4 preferred host with AAAA records: \n";
var_dump(gethostbyname("www.google.com"));
echo "\nIPv6 preferred host (no A record, but CNAME to A)\n";
var_dump(gethostbyname2("ipv6.google.com"));
echo "\nIPv4 preferred host with AAAA records:\n";
var_dump(gethostbyname2("www.google.com"));
echo "\nIPv4 preferred host with AAAA records and extra argument:\n";
var_dump(gethostbyname2("www.google.com",TRUE));
root@lucid32:/vagrant/php-5.4.13# ./sapi/cli/php run.php
IPv6 preferred host (no A record, but CNAME to A):
string(15) "ipv6.google.com"
IPv4 preferred host with AAAA records:
string(14) "173.194.66.103"
IPv6 preferred host (no A record, but CNAME to A)
string(22) "2a00:1450:400c:c05::68"
IPv4 preferred host with AAAA records:
string(14) "173.194.66.104"
IPv4 preferred host with AAAA records and extra argument:
string(22) "2a00:1450:400c:c03::68"
