php實現簽到功能

首先我在數據庫里建了兩張表,一個是用戶的積分表,一個是簽到狀態表,分來用來記錄用戶的積分數和先到狀態

 

在用戶簽到狀態表中我們有一個字段,last_sign_time,即上一次簽到時間,每次可以簽到的時候把這個時間與當前時間進行比較 如果相差為0天,則說明今天已簽到(這個簽到是24小時內只能簽到一次,即兩次簽到時間要相差24小時以上).如果等於一天則今日可以簽到,如果2天及其以上則說明漏簽了.

通過時間戳的判斷,及時更新狀態表,並且當可以簽到的時候則對用戶積分表進行操作,即更新用戶積分.

 

<?php
$user_id=@$_REQUEST['user_id'];
//功能：計算兩個時間戳之間相差的日時分秒
//$begin_time  開始時間戳
//$end_time 結束時間戳
function timediff($begin_time,$end_time)
{
      if($begin_time < $end_time){
         $starttime = $begin_time;
         $endtime = $end_time;
      }else{
         $starttime = $end_time;
         $endtime = $begin_time;
      }

      //計算天數
      $timediff = $endtime-$starttime;
      $days = intval($timediff/86400);
      //計算小時數
      $remain = $timediff%86400;
      $hours = intval($remain/3600);
      //計算分鍾數
      $remain = $remain%3600;
      $mins = intval($remain/60);
      //計算秒數
      $secs = $remain%60;
      $res = array("day" => $days,"hour" => $hours,"min" => $mins,"sec" => $secs);
      return $res;
