PHP sign-in, with time access

In this paper, we describe the method of PHP implementing check-in function. Share to everyone for your reference, as follows:
First of all, I built two tables in the database, one is the user's integration table, one is the check-in status table, which is used to record the user's number of points and first-to-state

In the User Registration status table We have a field, last_sign_time, that is, the last check-in time, each time you can check in to compare this time with the current time if the difference is 0 days, then the registration is today (this check-in is 24 hours can only sign in once, That is, two check-in time is 24 hours or more. If it is equal to one day, you can sign in today, if the 2 days and above indicate the missing sign.
Through the judge of timestamp, update the state table in time, and when can check-in, the User integration table is operated, that is, update the user points.
<?php
[Email protected]$_request[' user_id '];
Function: Calculates the difference between two time stamps in days and seconds
$begin _time start timestamp
$end _time End Timestamp
function Timediff ($begin _time, $end _time)
{
if ($begin _time < $end _time) {
$starttime = $begin _time;
$endtime = $end _time;
}else{
$starttime = $end _time;
$endtime = $begin _time;
}
Count Days
$timediff = $endtime-$starttime;
$days = Intval ($timediff/86400);
Count hours
$remain = $timediff% 86400;
$hours = intval ($remain/3600);
Count the number of minutes
$remain = $remain% 3600;
$mins = Intval ($remain/60);
Calculate the number of seconds
$secs = $remain% 60;
$res = Array ("Day" and "$days", "hour" + $hours, "min" = = $mins, "SEC" and "$secs");
return $res;
}
function Upuserscore ($current _total_day) {

INI file to read database configuration information

Check if there is a user in the integration table, then update the data without inserting the data

According to the last check-in time and the check-in time to make a comparison to determine whether the missing sign and today is registered
