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']) ? $_get['act'] : "error";
// d($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;
