PHP ftp_put警告警告：ftp_put()[function.ftp-put]：键入设置为

警告：ftp_put()[function.ftp-put]：无数据连接

现在,我尝试将被动模式放在：

ftp_pasv($conn_id,true);

然后出现错误：

警告：ftp_put()[function.ftp-put]：键入设置为I. in

ftp_login已正确完成,并表示已成功完成.

现在它给出了新警告：警告：ftp_put()[function.ftp-put]：abc.txt：无法打开或删除包含正在运行的程序的文件.

任何想法,为什么文件不转移？

谢谢 ！

这是我的代码片段：

$conn_id = ftp_connect($ftp_server) or die("Couldn't connect to $ftp_server");

    $login_result = ftp_login($conn_id,$ftp_user_name,$ftp_user_pass) or die("You do not have access to this ftp server!");

    if ((!$conn_id) || (!$login_result)) {
        // wont ever hit this,b/c of the die call on ftp_login
        echo "<span style='color:#FF0000'><h2>FTP connection has failed! <br />";
        echo "Attempted to connect to $ftp_server for user $ftp_user_name</h2></span>";
        exit;
    } else {
        //echo "Connected to $ftp_server,for user $ftp_user_name <br />";
    }

    //turn passive mode on
    ftp_pasv($conn_id,true);

    $upload = ftp_put($conn_id,$destination_file.$name,$filename,FTP_BINARY);

    if (!$upload) {
        echo "<span style='color:#FF0000'><h2>FTP upload of $filename has failed!</h2></span> <br />";
    } else {
        echo 'Uploaded';    
    }

 ftp_close($conn_id);
