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

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)
