Description:
------------
self signed certificates seem to be accepted when using the protocol wrappers regardless of the allow_self_signed stream context

the ftp package seems to reject self signed certificates however.

Test script:
---------------
$con=stream_context_create(array('ssl'=>array('allow_self_signed',false)));
var_dump(file_get_contents('ftps://John:pass@selfsigned.example.com/test.php,false,$con'));

$ftp=ftp_ssl_connect('selfsigned.example.com');
ftp_login($ftp,'John','pass');

Expected result:
----------------
file_get_contents and ftp_login should both throw some sort of error to the effect of "SSL/TLS handshake failed"

Actual result:
--------------
file_get_contents retrieves the file with no warnings

ftp_login throws the error "SSL/TLS handshake failed"
