Description:
------------
My system has 2 ip addresses, one ipv4 (A.B.C.D) and the other ipv6 (1:2:3:4:5:6)

I'm trying to open a file over HTTP (http://other.server/my.file.dat), 'other.server' is resolving both on ipv4 and ipv6 too.

I'd like to choose wether IPv4 or IPv6 to open the file so I'm using stream_context_create() with the 'bindto' option.

'bindto' with an ipv4 address is NOT working
'bindto' with an ipv6 address is working


Reproduce code:
---------------
The following code is working (ipv6 is used)
--
$opts = array(
  'socket' => array(
      'bindto' => '[1:2:3:4:5:6]:0',
  ),
);

$context = stream_context_create($opts);

$contents = file_get_contents('http://other.server/my.file.dat', FALSE, $context);
--

The following code is NOT working:
--
$opts = array(
  'socket' => array(
      'bindto' => 'A.B.C.D:0',
  ),
);

$context = stream_context_create($opts);

$contents = file_get_contents('http://other.server/my.file.dat', FALSE, $context);
--

=> PHP Warning:  file_get_contents(): Invalid IP Address: A.B.C.D 

Expected result:
----------------
ipv4 working

Actual result:
--------------
ipv4 NOT working
