Working with Sessions

Written by @m_k_amin 21 November 2012

Sessions are an important resource to save data on the server. This script shows their usage by a simple example. In this example a random number is made and saved to a session; based on its value, a message is shown. If it is bigger than 5000, the 'ID' session is removed and the 'lottery' session is set to 'no'; otherwise it will be kept and 'lottery' session is set to 'yes'. Finally all data is removed.

Code Snippet:

                                                
                                                <!-- this script is provided by https://www.phpfreecode.com coded by: Kerixa Inc. -->

<?php
session_start();
$a= rand(1000, 9999);
echo "Your random ID is $a.<br>";
$_SESSION['ID']= $a;
if ($a>=5000) {
          session_unset('ID');
          echo 'Sorry Bad Chance.';
          $_SESSION['lottery']= 'no';}
else{
          $b= $_SESSION['ID'];
          echo "Good Chance and you will be added to the Lottery with $b ID.";
          $_SESSION['lottery']= 'yes';}
session_destroy();
?>
