推荐答案

您需要指定要上传到FTP服务器的本地文件(从Web服务器开始).

You need to specify what local file (as of the webserver) you want to upload to the FTP server.

您可以使用 .阅读有关PHP中 POST方法上传的信息.

You can retrieve a name of a temporary file that contains a file uploaded via HTTP POST from user's machine to your webserver using $_FILES["filename"]["tmp_name"]. Read about POST method uploads in PHP.

然后您可以将其传递给 ftp_put (无需ftp_fput):

You can then pass that to ftp_put (no need for ftp_fput):

ftp_put($ftp_conn, $target_dir.$target_file, $_FILES["filename"]["tmp_name"], FTP_IMAGE)

您的代码中还有两个其他问题(不是您遇到的直接问题，但是您将在解决后立即面对它们):

Two other issues in your code (which are not your immediate problems, but you will face them right after you resolve it):

• 如果要上传二进制文件(例如.mp3)，则绝对不要使用FTP_ASCII.使用FTP_IMAGE.

• Absolutely do not use FTP_ASCII, if you are uploading binary files, like .mp3. Use FTP_IMAGE.

您需要使用ftp_pasv .
