PHP implements check-in function (case)

This article mainly introduces the method of realizing the check-in function in PHP, and analyzes the related skills of PHP to realize the check-in function based on the database and time judgment operation in the form of examples. Friends in need can refer to the following

The examples of this article are described How to implement the check-in function in PHP. Share it with everyone for your reference, the details are as follows:

First of all, I built two tables in the database, one is the user's points table, and the other is the sign-in status table, which is used to record the user's points and First arrival status

In the user sign-in status table we have a field, last_sign_time, which is the last sign-in time, and you can sign in every time When comparing this time with the current time, if the difference is 0 days, it means you have checked in today (this check-in can only be done once in 24 hours, that is, the difference between the two check-ins must be more than 24 hours). If it is equal to one day, it means today You can sign in. If it is 2 days or more, it means you missed the sign.

Judging by the timestamp, the status table is updated in a timely manner, and when it is possible to sign in, the user points table is operated, that is, the user points are updated. .

The specific code is as follows:

<?php
$user_id=@$_REQUEST[&#39;user_id&#39;];
//功能：计算两个时间戳之间相差的日时分秒
//$begin_time 开始时间戳
//$end_time 结束时间戳
function timediff($begin_time,$end_time)
{
   if($begin_time < $end_time){
     $starttime = $begin_time;
     $endtime = $end_time;
   }else{
     $starttime = $end_time;
     $endtime = $begin_time;
   }
   //计算天数
   $timediff = $endtime-$starttime;
   $days = intval($timediff/86400);
   //计算小时数
   $remain = $timediff%86400;
   $hours = intval($remain/3600);
   //计算分钟数
   $remain = $remain%3600;
   $mins = intval($remain/60);
   //计算秒数
   $secs = $remain%60;
   $res = array("day" => $days,"hour" => $hours,"min" => $mins,"sec" => $secs);
   return $res;
}
