Description:
------------
I've played with the ftps wrapper, but some issues with it.

- scandir() doesn't work at all. (test 1)
- With file_get_contents() I get the content, but also a warning. (test 2)
(the same behaviour I have with an older PHP (5.0.4) on *nix with both tests)

- An additional test with ftp_ssl_connect() works only on *nix (PHP 5.0.4) but not on Windows (PHP 5.1.4, not an official build). (test 3)

With some other ftp clients, I have no problems.


Reproduce code:
---------------
*** TEST 1 ***
[php script]
<?php
error_reporting(E_ALL);
print_r(scandir('ftps://foo:bar@bsdserver-1-node3:21/'));
?> 


*** TEST 2 ***
[explorer.bat (file on ftp server)]
cd \
cd Windows
explorer.exe
pause

[php script]
<?php
error_reporting(E_ALL);
print_r(file_get_contents('ftps://foo:bar@bsdserver-1-node3:21/anonymous/tmp/explorer.bat'));
?>


*** TEST 3 ***
[php script]
<?php
error_reporting(E_ALL);
$conn_id = ftp_ssl_connect('bsdserver-1-node3', 21);
$login_result = ftp_login($conn_id, 'foo', 'bar');
$contents = ftp_nlist($conn_id, '/');
var_dump($contents);
?> 


Expected result:
----------------
It should work (and without warnings) ;-)

But I have logs with working connections from a ftp client (connect / list directory / disconnect) on the same windows box as PHP:

I was able to reproduce Test 1 (issue with scandir()) with 5.6.13 as well as and today's php-src/master from github.

Problem with scandir() is fixed with the same patch as opendir() problem listed in bug #54431.
