本文实例讲述了PHP连续签到功能实现方法。分享给大家供大家参考,具体如下:

require "./global.php";
  $act = isset($_GET['act']) "error";
  // d($act);
  switch($act){
    case "qiandao":
      $uid = intval($_POST['uid']);
      $res = $db -> get('qian_dao','*',array('uid'=>$uid));
      // last_query();
      $time = time();
      //判断今天是否签到
      $todayBegin=strtotime(date('Y-m-d')." 00:00:00"); 
      $todayEnd= strtotime(date('Y-m-d')." 23:59:59"); 
      $isexit = $db -> get('qian_dao','id',array('AND'=>array('uid'=>$uid,'qian_dao_time[>=]'=>$todayBegin,'qian_dao_time[<=]'=>$todayEnd)));
      // last_query();
      if($isexit){
        // echo "今天已签到!";
        Log::writeLog(print_r(array('state'=>'stop','msg'=>'今天已签到!'),true));
        echo json_encode(array('state'=>'stop','msg'=>'今天已签到!'));
        exit;
      }
      if($res){
        //存在签到
        if((time() - $res['qian_dao_time'] > 24*60*60)){ // 判断时间是否大于24小时
          // 让字段归0
          $addInfo = $db -> update('qian_dao',array('qian_dao_num'=>1,'qian_dao_time'=>$time),array('uid'=>$uid));
        }else{
          // 更新签到的天数
          $addInfo = $db -> update('qian_dao',array('qian_dao_num[+]'=>1,'qian_dao_time'=>$time),array('uid'=>$uid));
        }
      }else{
        // echo '您还没有签到过';
        //没有签到过
        $db -> insert('qian_dao',array('uid'=>$uid,'qian_dao_num'=>1,'qian_dao_time'=>$time));
        // echo $db ->last_query();
      }
      // 插入签到记录
      $db -> insert('sign',array(
        'uid'=>$uid,
        'dateline'=>$time,
      ));
      // 获取连续签到的天数
      $info = $db -> get('qian_dao','qian_dao_num',array('uid'=>$uid));
      echo json_encode(array('state'=>'success','msg'=>"您是第".$info."天签到"));
      break;
    default :
      echo json_encode(array("ret"=>0,"msg"=>"操作不存在!"));
      break;
  }

sql:

CREATE TABLE IF NOT EXISTS `qian_dao` (
 `id` int(11) NOT NULL AUTO_INCREMENT,
 `uid` int(1) NOT NULL COMMENT '用户id',
 `qian_dao_num` int(11) NOT NULL COMMENT '签到次数',
 `qian_dao_time` int(11) NOT NULL COMMENT '签到时间',
 PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
CREATE TABLE IF NOT EXISTS `sign` (
 `uid` int(11) NOT NULL,
 `dateline` varchar(10) COLLATE utf8_bin NOT NULL,
 KEY `uid` (`uid`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_bin;

html:

<" 00:00:00"); 
  $todayEnd= strtotime(date('Y-m-d')." 23:59:59"); 
  $isexit = $db -> get('qian_dao','id',array('AND'=>array('uid'=>$uid,'qian_dao_time[>=]'=>$todayBegin,'qian_dao_time[<=]'=>$todayEnd)));
  $flag = '';
  if($isexit){
    $flag = 'current';
  }
