FTP copy a file to another place in same FTP

Question

I need to upload same file to 2 different place in same FTP. Is there a way to copy the file on the FTP to the other place instead of upload it again? Thanks.

The code below makes the FTP server to upload the file to itself (using loopback connection). It needs the FTP server to allow both passive and active connection mode.

If you want to understand the ftp commands here is a list of them : List of ftp commands

function copyFile($filePath, $newFilePath)
{
    $ftp1 = ftp_connect('192.168.1.1');
    $ftp2 = ftp_connect('192.168.1.1');
    ftp_raw($ftp1, "USER ftpUsername");
    ftp_raw($ftp1, "PASS mypassword");
    ftp_raw($ftp2, "USER ftpUsername");
    ftp_raw($ftp2, "PASS mypassword");

    $res = ftp_raw($ftp2, "PASV");
    $addressAndPort = substr($res[0], strpos($res[0], '(') + 1);
    $addressAndPort = substr($addressAndPort, 0, strpos($addressAndPort, ')'));

    ftp_raw($ftp1, "CWD ." . dirname($newFilePath));
    ftp_raw($ftp2, "CWD ." . dirname($filePath));
    ftp_raw($ftp1, "PORT ".$addressAndPort);

    ftp_raw($ftp1, "STOR " . basename($newFilePath));
    ftp_raw($ftp2, "RETR " . basename($filePath));

    ftp_raw($ftp1, "QUIT");
    ftp_raw($ftp2, "QUIT");
}
