php，curl-打印目录和文件列表，而不是其他不是目录的网页

Question

我希望$ matches [1]获取文件名和目录名，而不是其他网页。

 $link="some/remote/directory";

$ch = curl_init();
$hohoho ='$1'.$link.'$2$3';
curl_setopt($ch, CURLOPT_URL,$link );
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT ,4); 
curl_setopt($ch, CURLOPT_TIMEOUT, 4);
curl_setopt($ch, CURLOPT_BUFFERSIZE, 128); // more progress info

$result = curl_exec($ch);
curl_close($ch);
$result = preg_replace("#(<\s*a\s+[^>]*href\s*=\s*[\"'])(?!http)([^\"'>]+)([\"'>]+)#",$hohoho, $result);   


 if(preg_match('#<ul[^>]*>(.+?)</ul>#is', $result, $matches))
{foreach ($matches as &$match)

    $match = $match;
     echo '<ul>' . $matches[1] . '</ul>';

}
