PHP ftp_put 失败

Question

我通过 FTP 上传 XML 文件：

$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";
}

我想将使用DOMDocument 创建的 XML 文件发送到 FTP 服务器，但我不能。

ftp_put 返回 false。

Answer 1

ftp_put（或任何其他传输命令，如ftp_get、ftp_nlist、ftp_rawlist、ftp_mlsd）出现问题的最典型原因是 PHP 默认为活动模式。在 99% 的情况下，必须切换到被动模式才能使传输正常工作。使用ftp_pasv function。

$connect = ftp_connect($ftp) or die("Unable to connect to host");
ftp_login($connect, $username, $pwd) or die("Authorization failed");
// turn passive mode on
ftp_pasv($connect, true) or die("Unable switch to passive mode");

ftp_pasv 必须在 ftp_login 之后调用。之前调用它没有效果。

另见：

• PHP ftp_put fails with "Warning: ftp_put (): PORT command successful"
• 我的文章在active and passive FTP connection modes。

这行得通：

// connect and login to FTP server
$ftp_server = "host";
$ftp_username = "username";
$ftp_userpass = "password";
$ftp_conn = ftp_connect($ftp_server) or die("Could not connect to $ftp_server");
$login = ftp_login($ftp_conn, $ftp_username, $ftp_userpass);
$file ="$abc";

// upload file 
if (ftp_put($ftp_conn, "/$abc" , $file, FTP_ASCII)){
    echo "Successfully uploaded $file.";
} else {
    echo "Error uploading $file";
}

// close connection
ftp_close($ftp_conn);
