Basic usage example

<?php
$ctx = stream_context_create();
$params = array("notification" => "stream_notification_callback");
stream_context_set_params($ctx, $params);
var_dump(stream_context_get_params($ctx));

stream_context_set_params()Set parameters for a stream/wrapper/context

Note that if the resource parameter is invalid the function will return a boolean with value false.
The code:
$r = null
$cert = stream_context_get_params($r);
var_dump($cert);
will return:
bool(false)
