计算实际播种者的总数

Question

I'm creating a PHP torrent scraper based on the info hash of torrents. I managed to get the number of seeds and peers per torrent on a lot of trackers. But how do I calculate the 'average' number of seeds?

Is there something I can do with DHT maybe?

Answer 1

Wouldn't you just add up all the seeds per tracker, and divide that number by how many trackers there are if you want the average? I'm not sure of what info is stashed in the hash but this seems like a reasonable solution to calculate the average.

$seeds = 0;

foreach($tracker as $track) {
   /* 
    * Something along this line to add the current trackers
    * seeds to a $seeds variable
    */
   $seeds += $track['seeds'];
}

$average = $seeds / count($tracker);
