                  }
                  $d=dir($source);
                  while(($entry=$d->read())!==false){
                          if(is_dir($source.$entry)){
                                  if($entry=="."||$entry==".."){
                                          continue;
                                  }else{
                                          move_d("$source$entry//","$target$dest_name//");
