這篇文章將為大家詳細講解有關使用PHP怎么實現一個連續簽到功能，文章內容質量較高，因此小編分享給大家做個參考，希望大家閱讀完這篇文章后對相關知識有一定的了解。
具體如下：
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();
//判斷今天是否簽到
$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($isexit){
// echo "今天已簽到！";
Log::writeLog(print_r(array('state'=>'stop','msg'=>'今天已簽到！'),true));
echo json_encode(array('state'=>'stop','msg'=>'今天已簽到！'));
exit;
}
if($res){
//存在簽到
if((time() - $res['qian_dao_time'] > 24*60*60)){ // 判斷時間是否大于24小時
// 讓字段歸0
$addInfo = $db -> update('qian_dao',array('qian_dao_num'=>1,'qian_dao_time'=>$time),array('uid'=>$uid));
}else{
// 更新簽到的天數
$addInfo = $db -> update('qian_dao',array('qian_dao_num[+]'=>1,'qian_dao_time'=>$time),array('uid'=>$uid));
}
}else{
// echo '您還沒有簽到過';
//沒有簽到過
$db -> insert('qian_dao',array('uid'=>$uid,'qian_dao_num'=>1,'qian_dao_time'=>$time));
// echo $db ->last_query();
}
// 插入簽到記錄
$db -> insert('sign',array(
'uid'=>$uid,
'dateline'=>$time,
));
// 獲取連續簽到的天數
$info = $db -> get('qian_dao','qian_dao_num',array('uid'=>$uid));
echo json_encode(array('state'=>'success','msg'=>"您是第".$info."天簽到"));
break;
default :
echo json_encode(array("ret"=>0,"msg"=>"操作不存在！"));
break;
}sql：
