Right; this is documented[1] now.

Description:
------------
At least when the context is set to 'tcp' and the socket is opened with
stream_socket_client, the callback method defined with the notification parameters of
stream_context_set_params never get called.
And the current documentation is pointless regarding which wrapper actually support the
notifications.
As far as I can see ftp and http wrappers support it but tcp socket (or even file://) don't.
Callback notification function is the way to perform efficient and advanced monitoring on socket.
It should be invoked for the following events:
STREAM_NOTIFY_RESOLVE Yes
STREAM_NOTIFY_CONNECT Yes
STREAM_NOTIFY_AUTH_REQUIRED No
STREAM_NOTIFY_MIME_TYPE_IS No
STREAM_NOTIFY_FILE_SIZE_IS No
STREAM_NOTIFY_REDIRECTED No
STREAM_NOTIFY_PROGRESS Yes but optional
STREAM_NOTIFY_COMPLETED Yes
STREAM_NOTIFY_FAILURE Oh Yes
STREAM_NOTIFY_AUTH_RESULT No
STREAM_NOTIFY_SEVERITY_INFO Yes
STREAM_NOTIFY_SEVERITY_WARN Yes
STREAM_NOTIFY_SEVERITY_ERR Yes
Test script:
---------------
<?php
// define our callback method
function snc() { var_dump(func_get_args()); }
$ctx= stream_context_create();
stream_context_set_params($ctx, array("notification" => "snc"));
$uri= "htttp://www.example.net";
$socket = stream_socket_client($uri, $errno, $errstr, 0, STREAM_CLIENT_CONNECT, $ctx); // snc should
already have been called here for at least connection and resolv.
$line =fgets($socket); // get one line.
fclose($socket); // close the connection.
// Run the above lines and snc() never gets called.
Expected result:
----------------
1. Update documentation to let developers know the current state of the callback support
2. Have the callback method invoked when using socket streams for the following events (where
applicable).
Actual result:
--------------
The scn method never gets called.
