Example #1 stream_context_get_params() example
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 ));
?>
以上例程的输出类似于:
array(2) { ["notification"]=> string(28) "stream_notification_callback" ["options"]=> array(0) { } }

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)
