我正在使用我下载的课程；由于对 php 类和助手不太熟悉，我决定发布它，看看是否有更多经验的人可以为我遇到的错误提供一些帮助。

我正在使用这个调用脚本“torrenttest”中的函数

<?php
require_once 'Torrentmaker.php';

$torrent = new Torrent( 'file', 'http://fr33dom.h33t.com:3310/announce' );
$torrent->announce(array('udp://tracker.openbittorrent.com:80/announce', 
if ( ! $error = $torrent->error() ) // error method return the last error message
    $torrent->save('test2.torrent'); // save to disk
else
    echo '<br>DEBUG: ',$error;

问题是当“文件”在同一台服务器上时它工作正常；但是，当它调用远程服务器时，它会给出超时错误，或者只是创建一个没有大小的 torrent 文件（无法运行）

这是 Torrentmaker.php 的脚本

class Torrent {

    public function __construct ( $data = null, $meta = array(), $piece_length = 256 ) {
        if ( is_null( $data ) )
            return false;
        if ( $piece_length < 32 || $piece_length > 4096 )
            return self::set_error( new Exception( 'Invalid piece lenth, must be between 32 and 4096' ) );
        if ( is_string( $meta ) )
            $meta = array( 'announce' => $meta );
        if ( $this->build( $data, $piece_length * 1024 ) )
            $this->touch();
        else
            $meta = array_merge( $meta, $this->decode( $data ) );
        foreach( $meta as $key => $value )
            $this->{$key} = $value;
    public function content ( $precision = null ) {
        $files = array();
        if ( isset( $this->info['files'] ) && is_array( $this->info['files'] ) )
            foreach ( $this->info['files'] as $file )
                $files[self::path( $file['path'], $this->info['name'] )] = $precision ?

                    self::format( $this->info['length'], $precision ) :
                    $this->info['length'];
        return $files;
    }
    public function save ( $filename = null ) {
        return file_put_contents( is_null( $filename ) ? $this->info['name'] . '.torrent' : $filename, $this->encode( $this ) );
    }
static public function file_get_contents ( $file, $timeout = self::timeout, $offset = null, $length = null ) {
        if ( is_file( $file ) || ini_get( 'allow_url_fopen' ) ) {
            $context = ! is_file( $file ) && $timeout ? 
                stream_context_create( array( 'http' => array( 'timeout' => $timeout ) ) ) : 
                null;
            return ! is_null( $offset ) ? $length ?
                @file_get_contents( $file, false, $context, $offset, $length ) : 
                @file_get_contents( $file, false, $context, $offset ) : 
                @file_get_contents( $file, false, $context );
        } elseif ( ! function_exists( 'curl_init' ) )
            return self::set_error( new Exception( 'Install CURL or enable "allow_url_fopen"' ) );
        $handle = curl_init( $file );
        if ( $timeout )
            curl_setopt( $handle, CURLOPT_TIMEOUT, $timeout );
        if ( $offset || $length )
            curl_setopt( $handle, CURLOPT_RANGE, $offset . '-' . ( $length ? $offset + $length -1 : null ) );
        curl_setopt( $handle, CURLOPT_RETURNTRANSFER, 1 );
        $content = curl_exec( $handle );
        $size = curl_getinfo( $handle, CURLINFO_CONTENT_LENGTH_DOWNLOAD );
        curl_close( $handle );
        return ( $offset && $size == -1 ) || ( $length && $length != $size ) ? $length ?
            substr( $content, $offset, $length) :
            substr( $content, $offset) :
            $content;
public function errors() {
    return empty( self::$errors ) ?
        false :
        self::$errors;
}
