I'm trying to upload a file from my local pc(WinNT) to an ftp-server on a Linux machine.The PHP script is located on a web server(Apache) on the same Linux machine. Login works, but the following row results in an error message:
$upload = ftp_put($conn_id, $destination_file, $source, "FTP_BINARY");
Warning: error opening "C:\dir_name\filename.txt" (that's the local file)
Seems similar to your problem, so I'm dying to know how you solved it!
