### 范例

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));
    ?>

    array(2) {
      ["notification"]=>
      string(28) "stream_notification_callback"

      array(0) {

    }
