using expire session and page refresh to implement a counting game
- The page refresh every count
- When the count reach 60 the message display to the user
- Finally, the count start from zero again and the repeat count
create page (mycountpage.php)
- This is a simple PHP page without any PHP script.
- We let the page to be refresh every second.
- Page refresh: <meta http-equiv="refresh" content="1">
<html> <head> <meta http-equiv="refresh" content="1"> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Time out Page</title> </head> <body> </body> </html>
add session and PHP script
- We start the php session.
- Initialize the $time_diff=0 and $youhit=null;
<body> <?php session_start(); $time_diff = 0; $youhit = null; ?> </body>
add the count logic
- Add additional logic for checking the count
<?php
session_start();
$time_diff = 0;
$youhit = null;
// check to see if $_SESSION['timeout'] is set
if (isset($_SESSION['time'])) {
// count time
$inactive = 60;
$time_0 = time();
$time_1 = $_SESSION['time'];
$time_diff = $time_0 - $time_1;
if ($time_diff > $inactive) {
$youhit='Finaly, you won!!';
session_unset($_SESSION['time']);
}
} else {
// set when not set
$_SESSION['time'] = time();
}
?>
add the page body for user to see
- This page place to let user to see the count take place.
- And, display message when the count reaches 60.

$inactive = 60;
$time_0 = time();
$time_1 = $_SESSION['time'];
$time_diff = $time_0 - $time_1;
