我的脚本是：

 echo $ dest; 
 echo $ source; 
 $ upload = ftp_put（$ nyambungkeftp，$ dest，$ source，FTP_ASCII）; 
 
 
 //检查上传状态
 if（！$ upload）{
 echoFTP upload has failed！;

 echo上传$ source_file到$ ftp_server作为$ destination_file; 
} 
 
 //关闭FTP流
 ftp_close（$ nyambungkeftp）;

解决方案

PHP默认为活动的FTP模式。由于无处不在的防火墙/ NAT /代理，主动模式几乎无法运行。

几乎总是需要使用被动模式。

对于该呼叫， ftp_login 后的> ftp_pasv ：

  ftp_pasv（$ nyambungkeftp，true）; 
  

请参阅 my .net / eng / docs / ftp_modesrel =nofollow noreferrer> FTP连接模式，了解为什么您通常需要使用被动模式。

File is created on the FTP server, but its always 0 bytes large. Please give me a solution so that the file upload will working success.

I keep getting this warning:

Warning: ftp_put (): PORT command successful in C: \ xampp \ htdocs \ mailing \ teskirim-file-simpan2.php on line 30
FTP upload has failed!

My script is:

<?php
$ftp_server = "********";
$ftp_serverpath = "ftp.".$ftp_server;
$ftp_user_name = "********";
$ftp_user_pass = "***********";
$email_dir = "*******@*********";

$nyambungkeftp = ftp_connect($ftp_server);
if (false === $nyambungkeftp) {
    throw new Exception('Unable to connect');
}

$loggedInnyambungkeftp = ftp_login($nyambungkeftp,  $ftp_user_name,  $ftp_user_pass);
if (true === $loggedInnyambungkeftp) {
    echo 'Success!';
} else {
    throw new Exception('Unable to log in');
}

if ((!$nyambungkeftp) || (!$loggedInnyambungkeftp)) { 
        echo "FTP connection has failed!";
        echo "Attempted to connect to $ftp_server for user $ftp_user_name"; 
        exit; 
    } else {
        echo "Connected to $ftp_server, for user $ftp_user_name";
    }

// upload the file
$dest = 'detectip.txt';
$source = 'C:\xampp\htdocs\persuratan\file2\detectip.txt';

echo $dest;
echo $source;
$upload = ftp_put($nyambungkeftp, $dest, $source, FTP_ASCII); 


// check upload status
if (!$upload) { 
        echo "FTP upload has failed!";
    } else {
        echo "Uploaded $source_file to $ftp_server as $destination_file";
    }

// close the FTP stream 
ftp_close($nyambungkeftp); 

?>

解决方案

PHP defaults to the active FTP mode. The active mode hardly ever works these days due to ubiquitous firewalls/NATs/proxies.

You almost always need to use the passive mode.

For that call the ftp_pasv after the ftp_login:

ftp_pasv($nyambungkeftp, true);

See my article on FTP connection modes, to understand, why you typically need to use the passive mode.
