¿Cómo agregar una función de clase para completar a los compañeros en un torrent?

Question

¡He creado un script que genera información sobre un archivo torrent!¡Pero me falta crear una función de semillas y compañeros que muestran la función!Alguien me dijo que están en el campo completado definido en el torrente.Por favor, mis códigos de función de clase desde los que muestre la información generada con una bencode.php que saca los datos y este script, llamado torrent.php lo convierte en forma legible!

<?php

Answer 1

Little late but the class you say to have created comes from:

https://github.com/torrage/Torrage

It's original purpose was not intended to retrieve that kind of data.

A class that gets you seeds and peers for torrent inclusive the rest of the data see:

https://github.com/adriengibrat/torrent-rw

Answer 2

That information's not stored in the .torrent file. It's highly dynamic data, which can change every microsecond on a 'busy' torrent. The server's not going to build a custom .torrent file with up-to-the-minute statistics every time someone downloads it.

Think about it for a second. You download a .torrent file on Monday, but only look at it next Friday. The stats are now a week old and stale.

You can, however, take the tracker information in the .torrent and query those trackers for the stats.
