将文件夹上传到FTP服务器，遍历上传，，，文件夹不能直接上传到FTP服务器上。。。

<?

    $ftp_ip = "FTP";

    $ftp_user = "user";

    $ftp_pwd = "password";

    $conn = ftp_connect($ftp_ip);

    $login_result = ftp_login($conn, $ftp_user, $ftp_pwd);

        if($conn || $login_result){

    echo "Load FTP1 successful！";

        }else{

                 echo "Load FTP1 failed!";

        }

    echo "<br>";

    $dir = getcwd();    //根目录

    chdir("file");          //找到file文件夹

    $dir = getcwd();    //将文件路径更改为更：目录/file

    $creafile = ftp_mkdir($conn,"file");    //上传前建立文件夹file

    $handle = opendir("$dir");             

    while(($file = readdir($handle)) !== false)

    {

        $ftp = ftp_put($conn,"file/$file","$file",FTP_BINARY);   //遍历上传

    }

?>
