PHP's ftp_put operation failed

Question

I upload the XML file via FTP:

$ftp = "ftp";
$username = "username";
$pwd = "Password";
$filename = $_FILES[$xyz][$abc];
$tmp = $_FILES['file']['tmp_name'];
$destination = "/Content/EnquiryXML ";

$connect = ftp_connect($ftp)or die("Unable to connect to host");
ftp_login($connect,$username,$pwd)or die("Authorization failed");
echo "Connected!<br/>";

if(!$filename)
{
    echo "Please select a file";
}

else
{
    ftp_put($connect,$destination.'/'.$filename,$tmp,FTP_ASCII)or die("Unable to upload");
    echo "File successfully uploaded to FTP";
}

I want to send an XML file created using DOMDocument to an FTP server, but I cannot succeed.

ftp_put returns false.

Answer 1

This worked:

// 连接并登录到FTP服务器
$ftp_server = "主机";
$ftp_username = "用户名";
$ftp_userpass = "密码";
$ftp_conn = ftp_connect($ftp_server) or die("无法连接到 $ftp_server");
$login = ftp_login($ftp_conn, $ftp_username, $ftp_userpass);
$file ="$abc";

// 上传文件
if (ftp_put($ftp_conn, "/$abc" , $file, FTP_ASCII)){
    echo "成功上传文件 $file。";
} else {
    echo "上传文件 $file 出错";
}

// 关闭连接
ftp_close($ftp_conn);

Answer 2

results in ftp_put (or any other transfer command such as ftp_get, ftp_nlist, ftp_rawlist, ftp_mlsd ) The most common reason for problems is that PHP defaults to active mode. In 99% of cases, switching to passive mode is required for the transmission to work properly. Use ftp_pasvfunction.

$connect = ftp_connect($ftp) or die("无法连接到主机");
ftp_login($connect, $username, $pwd) or die("授权失败");
// 打开被动模式
ftp_pasv($connect, true) or die("无法切换到被动模式");

ftp_pasv must be called after ftp_login. Calling it before has no effect.

• PHP ftp_put fails, displaying "Warning: ftp_put (): PORT command successful"
• My article about active and passive FTP connection modes.

Additionally, if your FTP server reports the wrong IP address when responding to the PASV command (this is fairly common if the server is behind a firewall/NAT), you may need to do this by using solve:

ftp_set_option($connect, FTP_USEPASVADDRESS, false);

SeePHP FTP Passive FTP server is behind NAT.

Although in this case the correct solution is to repair the server.
