I am using the following function to perform batch FTP.
function ftp_putAll($conn_id, $src_dir, $dst_dir) {
   $d = dir($src_dir);
   while($file = $d->read()) { // do this for each file in the directory
       if ($file != "." && $file != "..") { // to prevent an infinite loop
           if (is_dir($src_dir."/".$file)) { // do the following if it is a directory
               if (!@ftp_chdir($conn_id, $dst_dir."/".$file)) {
                   ftp_mkdir($conn_id, $dst_dir."/".$file); // create directories that do not yet exist
               }
               ftp_putAll($conn_id, $src_dir."/".$file, $dst_dir."/".$file); // recursive part
           } else {
               $upload = ftp_put($conn_id, $dst_dir."/".$file, $src_dir."/".$file, FTP_BINARY); // put the files
           }
       }
   }
   $d->close();
}

But when I call the function, I keep getting the error:
Warning: dir(/www/cms_creator/trial/design_01/) [function.dir]: failed to open dir: Invalid argument in c:\Inetpub\wwwroot\tests\PHP\test8.php on line 4

Fatal error: Call to a member function read() on a non-object in c:\Inetpub\wwwroot\tests\PHP\test8.php on line 5

The first one might need the full path, but the second one is where I need help.
