Operating System: *
PHP Version: 5.*, 6CVS (2009-07-06)
New Comment:
Conveniently, I have a host name (ipv6.adamharvey.name) that only has
AAAA records, which simplifies testing somewhat. It has both regular
HTTP and Gopher servers -- Gopher's a particularly simple protocol to
test (send a newline, get an index), so it's quite useful in this case.
:)
This appears to be an issue somewhere in the streams code; I can
confirm that this is still occurring with the current PHP_5_3 branch
(tested on Linux). There's no dependency on whether a host name or IP
address are provided; both fail the same way. It's notable that no error
information is filled out, socket_stream_create() simply returns false
and sets errno to 0.
A direct AF_INET6 socket connection works as expected.
Tests:
HTTP wrapper:
<?php var_dump(file_get_contents('http://ipv6.adamharvey.name/')); ?>
Output:
Warning: file_get_contents(http://ipv6.adamharvey.name/): failed to
open stream: operation failed in /tmp/wrapper.php on line 1
Call Stack:
0.0001 629088 1. {main}() /tmp/wrapper.php:0
0.0001 629232 2. file_get_contents() /tmp/wrapper.php:1
bool(false)
Stream socket:
<?php
$errno = $errstr = null;
$r = stream_socket_client('tcp://[2002:cfc0:4611::1]:70/', &$errno,
&$errstr);
if ($r) {
fwrite($r, "\r\n");
$data = '';
while ($packet = fread($r, 16384)) {
$data .= $packet;
}
var_dump($data);
fclose($r);
}
else {
echo "Error: $errno; $errstr\n";
}
?>
Output:
Warning: stream_socket_client(): unable to connect to
tcp://[2002:cfc0:4611::1]:70/ (Unknown error) in /tmp/stream.php on line
3
Call Stack:
0.0002 634424 1. {main}() /tmp/stream.php:0
0.0002 634856 2. stream_socket_client() /tmp/stream.php:3
Error: 0;
Direct socket connection:
<?php
$sock = socket_create(AF_INET6, SOCK_STREAM, SOL_TCP) or
die(socket_strerror(socket_last_error()));
socket_connect($sock, '2002:cfc0:4611::1', 70) or
die(socket_strerror(socket_last_error()));
socket_write($sock, "\r\n");
$data = '';
while ($packet = socket_read($sock, 16384)) {
$data .= $packet;
}
var_dump($data);
?>
Output:
string(1230) "iFive Minutes / xn--9bi.net 70
<normal Gopher output snipped>
"
I can't see anything obvious in the 5.2.9 -> 5.2.10 diff that might
have caused this, but I'm hardly an expert on the streams code, so this
is likely to need someone more qualified to look at it. Hopefully this
helps isolate the problem somewhat -- if I can help test this further,
please let me know.

An example may be:
ipv6.google.com or ipv6.beijing2008.cn
(our in-house company servers are not accessible by the outside world)
But don't you think it's easier to test this with a local webserver
like Apache?
BTW:
It doesn't matter if this is an IPv6 only or a dual stack server.
Connections with the IPv6 address doesn't work. That's the point.

Can you provide an url to an ipv6 only server?

Also not working on Linux.

Same problem on OS X.

It's also not working with the latest snapshot.
