Ftp server to server upload

[pacard]

I want to upload the entire contents of a folder on one ftp server to another remote FTP server.

In the example, I'm trying to copy the entire "html" directory located in /public_html/html to a remote server's /public_html/test/ via FTP.

<?php

// --------------------------------------------------------------------
// THE TRIGGER
// --------------------------------------------------------------------

   // set the various variables
   $ftproot = "/public_html/test/";
   $srcroot = "/public_html/";        

   $srcrela = "html/";

   // connect to the destination FTP & enter appropriate directories both locally and remotely
   $ftpc = ftp_connect("ftp.mydomain.com");
   $ftpr = ftp_login($ftpc,"username","password");

   if ((!$ftpc) || (!$ftpr)) { echo "FTP connection not established!"; die(); }
   if (!chdir($srcroot)) { echo "Could not enter local source root directory."; die(); }
   if (!ftp_chdir($ftpc,$ftproot)) { echo "Could not enter FTP root directory."; die(); }

   // start ftp'ing over the directory recursively
   ftpRec ($srcrela);

   // close the FTP connection
   ftp_close($ftpc);

// --------------------------------------------------------------------
// THE ACTUAL FUNCTION
// --------------------------------------------------------------------
function ftpRec ($srcrela)
{
   global $srcroot;
   global $ftproot;
   global $ftpc;
   global $ftpr;

   // enter the local directory to be recursed through
   chdir($srcroot.$srcrela);

   // check if the directory exists & change to it on the destination
   if (!ftp_chdir($ftpc,$ftproot.$srcrela))
   {
       // remote directory doesn't exist so create & enter it
           ftp_mkdir    ($ftpc,$ftproot.$srcrela);
           ftp_chdir    ($ftpc,$ftproot.$srcrela);
   }

   if ($handle = opendir("."))
   {
       while (false !== ($fil = readdir($handle)))
       {
           if ($fil != "." && $fil != "..")    

           {
               // check if it's a file or directory
               if (!is_dir($fil))
               {    

                   // it's a file so upload it
                   ftp_put($ftpc, $ftproot.$srcrela.$fil, $fil, FTP_BINARY);
               }
               else
               {
                   // it's a directory so recurse through it
                   if ($fil == "templates")
                   {
                           // I want the script to ignore any directories named "templates"
                           // and therefore, not recurse through them and upload their contents
                   }
                   else
                   {
                       ftpRec ($srcrela.$fil."/");
                       chdir ("../");
                   }
               }
         }
     }
     closedir($handle);
   }    

}
?> 

It does not work , what changes should I make to make it work..
