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：
