What is the reason for that failure? How do I determine this?
It seems strange that the "intended behavior" would be to fail without giving the user any
means whatsoever to correct the failure.

Description:
------------
gethostbyname() fails to return an IP; dns_get_record() works.
No error message of any kind is generated.
This happens for any domain I've tried.
Test script:
---------------
<pre>
<?
$domain='www.example.com';
echo "gethostbyname($domain)\n";
var_dump(gethostbyname($domain));
echo "\n";
echo "dns_get_record($domain,DNS_A)\n";
var_dump(dns_get_record($domain,DNS_A));
echo $notice;
fopen('warning','r');
Expected result:
----------------
gethostbyname(www.example.com)
string() "192.0.43.10"
dns_get_record(www.example.com,DNS_A)
array(1) {
[0]=>
array(5) {
["host"]=>
string(15) "www.example.com"
["type"]=>
string(1) "A"
["ip"]=>
string(11) "192.0.43.10"
["class"]=>
string(2) "IN"
["ttl"]=>
int(3020)
}
}
Notice: Undefined variable: notice in /www/dev/dynamic/test.php on line 14
Warning: fopen(warning): failed to open stream: No such file or directory in
/www/dev/dynamic/test.php on line 15
Actual result:
--------------
gethostbyname(www.example.com)
string(15) "www.example.com"
dns_get_record(www.example.com,DNS_A)
array(1) {
[0]=>
array(5) {
["host"]=>
string(15) "www.example.com"
["type"]=>
string(1) "A"
["ip"]=>
string(11) "192.0.43.10"
["class"]=>
string(2) "IN"
["ttl"]=>
int(3020)
}
}
