@terrytibs: hmmmm.... the btjunkie API! I will definitely take a look into it. It would mean than btjunkie MUST remain operational at all times though, as my service would then depend on constant connectivity to btjunkies servers. I have noticed their site go down at times too. Do you know if they count seeders from all trackers, or just seeders on the btjunkie tracker? Also, do they include DHT seeds and peers in their results? Very interesting indeed.
I will research into this later today.Another thing, use torrenteditor.com's bencode and torrent classes.
bencode include: http://pastebin.com/LfmPYkXQ
torrent include: http://pastebin.com/HQSH8SYY
Now you can simply get the hash by doing
Code:
set_include_path('include');
include_once('torrent.php');
$data = file_get_contents($grab_from_file_upload);
if ($data == false) {
exit("Couldn't read torrent.");
}
$torrent = new Torrent();
if ($torrent->load($data) == false) {
exit("Error: {$torrent->error}");
}
$hash = $torrent->getHash();
// Eye candy, skip this for if-statements
$hash = chunk_split($hash, 8, ' ');
echo($hash);Edit: About the connectivity, you could just set the timeout pretty low. The world doesn't end if the torrent has a low seeder-count. You should, however, refund the user if there are no seeders and the download doesn't start within a set timeframe.
Second edit: isoHunt has a JSON-search-api. It would be better than btjunkie for getting results, although worse for actually parsing seed info and the like.
