Php 如何在torrent中添加类函数以获得完整的对等点？

我已经创建了一个脚本，可以生成有关torrent文件的信息！但我缺少创建种子和同伴显示功能！有人告诉我，它们位于torrent中定义的已完成字段中。请输入我的类函数代码，我使用一个bencode.php显示生成的信息，这个脚本名为torrent.php将其转换为可读形式

<?php
include_once('bencode.php');

该信息未存储在.torrent文件中。这是高度动态的数据，在“繁忙”的洪流中每微秒都会发生变化。服务器不会在每次有人下载时生成带有最新统计信息的自定义.torrent文件

想一想。您在周一下载了一个.torrent文件，但只能在下周五查看。这些数据已经过时一周了

但是，您可以在.torrent中获取跟踪器信息，并查询这些跟踪器的统计信息。
虽然有点晚，但您所说创建的类来自：


它最初的目的不是为了检索这种数据

为torrent（包括其余数据）获取种子和对等点的类请参见：

那么，您能告诉我如何发送种子和对等方获取生成的跟踪列表请求吗？这将在bittorent协议规范中，该规范在大多数地方都免费提供。
