使用PHP时如何获取FTP错误 [英] How to get the FTP error when using PHP

问题描述

我有一个脚本，登录到远程服务器，并尝试使用PHP重命名文件。

I have a script which logs on to a remote server and tries to rename files, using PHP.

代码目前看起来像PHP的这个例子。 net网站：

The code currently looks something like this example from the php.net website:

if (ftp_rename($conn_id, $old_file, $new_file)) {
 echo "successfully renamed $old_file to $new_file\n";
} else {
 echo "There was a problem while renaming $old_file to $new_file\n";
}

但是...是什么错误？权限，没有这样的目录，磁盘已满？

but ... what was the error? Permissions, no such directory, disk full?

如何让PHP返回FTP错误？这样的东西：

How can I get PHP to return the FTP error? Something like this:

echo "There was a problem while renaming $old_file to $new_file: 
the server says $error_message\n";

推荐答案

在这里查看FTP API：

Looking at the FTP API here:

http：// us。 php.net/manual/en/function.ftp-rename.php

似乎没有什么办法可以得到任何东西，但是真的或假的

There doesn't seem to be any way to get anything but true or false.

但是，您可以使用ftp_raw发送一个原始的RENAME命令，然后解析返回的消息。

However, you could use ftp_raw to send a raw RENAME command, and then parse the returned message.
