使用https://github.com/kaysond/deluge-php 提供的类，简单使用：
$host = "192.168.168.5:8112";
$password = "deluge";
$d = new deluge($host, $password);
//返回只包含当前状态Downloading中的
$filter = array('state' => "Downloading");
//返回指定的这此参数的值
$params = array('name', 'hash', 'max_upload_speed', 'eta');
$list = $d->getTorrentsStatus($filter, $params, '');
var_dump($list);
$url = 'https://www.haiyun.me/deluge.torrent';
$options = array('max_upload_speed' => 100, 'max_download_speed' => 100);
$res = $d->addTorrentUrl($url, $options, '');
var_dump($res);参考：
