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;

html：

include './global.php';

$uid = 1;

$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)));

$flag = '';

if($isexit){

$flag = 'current';

}

?>

jquery制作每天或每日打卡签到特效

$(document).ready(function(){

var cache=new Array(); // 缓存变量，当数据被访问过之后放置在缓存中，加快访问速度

$(".singer_r_img").click(function(){

// 如果缓存中存在数据，那么直接从缓存中读取；如果不存在数据，那么就从数据库中读取，并把数据存入缓存

if (typeof(cache['stop'])=='undefined') {

$.ajax({

type:"post",

dataType:'json',

data:{

uid:1,

})

// 获取签到记录

$sign = $db -> select('sign','*',array('uid'=>$uid,'ORDER'=>'dateline DESC'));

?>

if(empty($sign)){

?>

暂无签到信息

}else{

foreach($sign as $k=>$v){

?>

<?php echo ($k + 1);?> <?php echo date('Y-m-d H:i:s',$v['dateline']);?>

}

}

?>
