传输后ftp_put损坏了我的电影，是吗?

我有很多电影正试图从CentOS服务器传输到Windows PC.但是，当我通过此脚本运行它们时，它们最终会损坏.脚本有什么问题吗?

I have a bunch of movies that I'm trying to transfer from my CentOS server onto my Windows PC. But when I run them through this script they end up being corrupt. Is there something wrong with the script?

谢谢

$allFiles = glob("/var/www/html/ftp_pending/*");

// set up basic connection
$conn_id = ftp_connect($ftp_server);

// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

foreach($allFiles as $singleFile)
{
    // check if a file exist
    $path = "/"; //the path where the file is located

    $file = substr( $singleFile, strrpos( $singleFile, '/' )+1 );

    $check_file_exist = $path.$file; //combine string for easy use

    // Returns an array of filenames from the specified directory on success or
    // FALSE on error. 
    $contents_on_server = ftp_nlist($conn_id, $path); 

    // Test if file is in the ftp_nlist array
    if (in_array($check_file_exist, $contents_on_server)) 
    {
        echo "$file is already on FTP Server, no need to re-upload <br />";;
    }
    else
    {
        $localfile = '/var/www/html/'.$file.'';
        $remote_file = $file;

        // upload a file
        if (ftp_put($conn_id, $remote_file, $localfile, FTP_ASCII))
        {
             echo "successfully uploaded $file\n";
        }
        else
        {
             echo "There was a problem while uploading $file\n";
        }
    };

}

// remember to always close your ftp connection
ftp_close($conn_id);
