Assuming you are trying to access the remote server using HTTP, you won't be able to do this directly. Since HTTP is really going access the web service of your remote server, it controls how the files are presented to you. In the case of many web servers, you can turn on "indexes" for folder contents. This causes the entries in the folder to be displayed in your browser as HTML. In order to traverse the directory structure, you would need to parse this HTML to find the path information.
假设您尝试使用 HTTP 访问远程服务器，您将无法直接执行此操作。由于 HTTP 确实要访问远程服务器的 Web 服务，因此它控制着文件的呈现方式。对于许多 Web 服务器，您可以打开文件夹内容的“索引”。这会导致文件夹中的条目在浏览器中显示为 HTML。为了遍历目录结构，您需要解析此 HTML 以查找路径信息。
If you are using FTP, you can pass the ftp://...URL to opendir()as of version 5.0. Note that this capability can be turned off by your server admin. If you cannot use this feature directly, see the FTP functionsmanual for PHP (including ftp_nlist()for listing files).
如果您使用的是 FTP，则可以将ftp://...URL传递到opendir()版本 5.0。请注意，您的服务器管理员可以关闭此功能。如果您不能直接使用此功能，请参阅PHP的FTP 函数手册（包括ftp_nlist()列表文件）。
An example from the above references:
以上参考资料中的一个例子：
<?php
// set up basic connection
$conn_id = ftp_connect($ftp_server);
// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
// get contents of the current directory
$contents = ftp_nlist($conn_id, ".");
// output $contents
var_dump($contents);
?>

For files/folders that are visible to the public you can do it with this script: No FTP, no strugglin. It will give you back all filenames in a remote folder. If you can open the folder with a browser, you can also read it with php. Happy leeching ;)
对于对公众可见的文件/文件夹，您可以使用以下脚本执行此操作：没有 FTP，没有挣扎。它将返回远程文件夹中的所有文件名。如果可以用浏览器打开文件夹，也可以用php阅读。快乐偷窃 ;)
UPDATE: This only lists the files that are available for the public, for sure not files that are only visible for a certain user!
更新：这仅列出了对公众可用的文件，当然不是仅对特定用户可见的文件！
function get_text($filename) {
$fp_load = fopen("$filename", "rb");
if ( $fp_load ) {
while ( !feof($fp_load) ) {
$content .= fgets($fp_load, 8192);
}
fclose($fp_load);
return $content;
}
}
$matches = array();
preg_match_all("/(a href\=\")([^\?\"]*)(\")/i", get_text('http://www.xxxxx.com/my/cool/remote/dir'), $matches);
foreach($matches[2] as $match) {
echo $match . '<br>';
}

Assuming you have the ftp extension loaded for php on your server, you should be able to use phps ftp functions
假设您在服务器上为 php 加载了 ftp 扩展，您应该能够使用phps ftp 函数
