用于PHP中修改的Torrent编辑器的UDP Scrapper

Question

我们正在做一个网站，您可以在其中编辑torrent文件的跟踪器。

我们正在搜索TRACKER的SEEDS和PEERS。

我们很困惑它是如何工作的。有没有人知道如何在PHP中显示torrent文件的SEEDS和PEERS？

就像在TORRENTEDITOR.COM中，我们已经看到了这样的代码，但我们不明白它是如何工作的，请帮助我们。

// global $seedsandpeers; 
    if ($seedsandpeers === TRUE){ 
    if (!empty($array["announce-list"])){ 
     $announce = $array["announce-list"]; 
    // Possibly HtTp:// 
     $announce = strtolower($announce); 
    if (substr($announce, 0, 7) === "http://"){ 
     if ((substr_count($announce, "/announce")) == 1){ 
      $scrape = str_replace('/announce', '/scrape', $announce); 
      $httpget = "?info_hash="; 
      $binsha1 = pack("H*", $infohash); 
      $binsha1s = addslashes($binsha1); 
      $fullurl = "$scrape$httpget$binsha1"; 
      $httpurl = pathurlencode($fullurl); 
    sapeerconnect($httpurl, $binsha1s, $torrentsize); 
    } else { 
$error = '<BR><label style="font-family:timesnewroman;font-size:12px;">Bad Tracker enter code hereURL for scraping (Maybe trackerless torrent).<br>' ; 
echo $error; 
} 
} 
else { 
$error = '<BR><label style="font-family:timesnewroman;font-size:12px;">Bad Tracker URL for scraping (Maybe trackerless torrent).<br>'; 
echo $error; 
} 
} 
}

所以我研究了一下，它看起来像你可以解码的.torrent文件：$

<?php 
include 'functions.php'; 

$torrent_data = bdec(file_get_contents('test.torrent')); 

$info=strtolower(sha1(benc($torrent_data['info']))); 
$scrape=str_replace('announce','scrape',$torrent_data['announce']); 
$sources=bdec(@file_get_contents($scrape.'?info_hash='.urlencode(hex2bin($info)))); 

$c=count($torrent_data['info']['files']); 
echo '<h2>Files</h2>'; 

$files=array(); 
if($c > 1) 
{ 
    for ($i = 0; $i < $c; $i++) $files[]=$torrent_data['info']['files'][$i]['path']['1']; 
    sort($files); 
    foreach($files as $file) echo $file."<br>"; 
} 
else echo $torrent_data['info']['name']."<br>"; 

$seeds = $sources['files'][hex2bin($info)]['complete']; 
$leechs = $sources['files'][hex2bin($info)]['incomplete']; 
$downloads = $sources['files'][hex2bin($info)]['downloaded']; 

echo '<h2>Sources</h2>'. 
    '<b>Seeds:</b> '.$seeds.'<br/>'. 
    '<b>Leechs:</b> '.$leechs.'<br/>' . 
    '<b>Downloads:</b> '.$downloads.'<br/>'; 
?> 

要使用此代码，您首先需要包括与台钳文件， bdec和hex2bin函数。您可以从Here

我已经准备了一个测试用例，可以发现Here

希望这有助于获得这些功能。
