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：
PHP代码：
<?php
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数据库：
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：
<?php
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';
}
