服务器端

  $objResponse->addAssign("pollresult","innerHTML",$tmp);

数据库的表如下

CREATE TABLE TBL_POLL (
  poll_id int(11) unsigned NOT NULL default '0',
  title varchar(100) NOT NULL default '',
  created_date bigint(20) unsigned NOT NULL default '0',
  user_id int(11) unsigned NOT NULL default '0',
  PRIMARY KEY  (poll_id)
) TYPE=MyISAM;

CREATE TABLE TBL_POLLITEM (
