Code for Beginners-session out Timer !
This is code is used as a session timeout timer and acts like set cookie. I use this code to set a five minutes session. You Can change the session timeout (in minutes) in the file named: end_timer.php
file 1 : login.php
==================
|
<?php
//start the time @ your login page
session_start();
$start=time();
$_SESSION['time_start']=$start;
/*get the login info & set to session */
?> | |
file 2 : home.php
=================
| <?php
$end=time();
include("start_timer.php");
include("end_timer.php");
/* session variables like user login info .. */
?> | |
file 3 : start_timer.php
========================
| <?php
$start=$_SESSION['time_start'];
$ItemStartDate=$start."<br>";
$ItemEndDate = $end."<br>";
// $Today = time();
$TimeLeft = $ItemEndDate - $ItemStartDate;
//$TimeLeft = $ItemEndDate - $ItemStartDate;
if($TimeLeft > 0)
{
$ADayInSecs = 24 * 60 * 60;
$Days = $TimeLeft / $ADayInSecs;
$Days = intval($Days);
$TimeLeft = $TimeLeft - ($Days * $ADayInSecs);
$Hours = $TimeLeft / (60 * 60);
$Hours = intval($Hours);
$TimeLeft = $TimeLeft - ($Hours * 60 * 60);
$Minutes = $TimeLeft / 60;
$Minutes = intval($Minutes);
$TimeLeft = $TimeLeft - ($Minutes * 60);
$Seconds = $TimeLeft;
$Seconds = intval($Seconds);
$TimeLeft = $TimeLeft - ($Seconds / 60 * 60 );
$MilliSeconds = $TimeLeft;
}
?> | |
file 4 : end_timer.php
===================
| <?php
$Seconds." Seconds " ;
$time_out=5;
if($Minutes<$time_out){
$_SESSION['time_start']=$end;
}else{
include("logout.php");
}
?> | |
file 5 : logout.php
===================
| <?php
//log out /session time out after 5 minutes of idle time
session_destroy();
?> | |
