PHP ftp_put 失败并返回 "Warning: ftp_put (): PORT command successful"

Question

文件在 FTP 服务器上创建，但其大小始终为 0 字节。请给我一个解决方案，以便文件上传成功。

我不断收到此警告:

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

我的脚本是:

<?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); 

?>

PHP 默认为主动 FTP 模式。由于无处不在的防火墙/NAT/代理，如今主动模式几乎无法工作。

你几乎总是需要使用被动模式。

为此调用 ftp_pasv 在 ftp_login 之后:

ftp_pasv($nyambungkeftp, true);

请参阅关于 FTP connection modes 的我文章，了解为什么您通常需要使用被动模式。
