发现官方类库没有FTP库，就随手写了一个，还不完善。
<?php <br />
class FTPAction extends CommonAction{<br>
public function index(){<br>
import('ORG.Util.Ftp');<br>
set_time_limit(0);<br>
$ftp=new FTP("222.2.2.200",21,"anonymous");<br>
foreach ($list as $v){<br>
if (!$ftp->isDir($v))<br>
$result.= "文件:".pathinfo(iconv('GBK', 'UTF-8', $v),PATHINFO_BASENAME)."<br>";<br>
else <br>
$result.= "目录:<a>".pathinfo(iconv('GBK', 'UTF-8', $v),PATHINFO_BASENAME)."</a><br>";<br>
} <br>
$this->assign('result',$result);<br>
$this->display();<br>
<br>
}<br>
}模板调用{$result}即可。<?php <br />
