Description:
------------
I'm not entirely sure if this is a bug or not, but when using the capture_peer_cert SSL context with a normal socket based stream connection (as opposed to it being asynchronous), I obtain the peer_certificate easily in the stream's context options.

When using it an asynchronous connection though, even after using stream select and the likes, I can't seem to capture the peer's certificate, even though I have the same context as used in the "normal" connections.

Reproduce code:
---------------
$ctx = stream_context_create ( array ( 'ssl' => array ( 'verify_peer'	    => false, 'capture_peer_cert' => true ) ) ) ; 

    $socket = stream_socket_client ( $host, $errno, $errstr, $timeout, STREAM_CLIENT_ASYNC_CONNECT|STREAM_CLIENT_CONNECT, $ctx ) ;

$info = stream_context_get_options ( $socket ) ;

print_r ( $info ) ;

Expected result:
----------------
Array
{
   [ssl] => Array
            {
               verify_peer => ,
               capture_peer_cert => 1,
               peer_certificate => Resource id #6
            }
}

Actual result:
--------------
Array
{
   [ssl] => Array
            {
               verify_peer => ,
               capture_peer_cert => 1,
            }
}
