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;
}
