<?php
session_start();
/*
If statement below saves a random number as session variable
so it won't change when a form is submitted multiple times
until the session is destroyed
*/
if(!isset($_SESSION['rand_num_session']))
{
$_SESSION['rand_num_session'] = rand(1, 100);
}
$_SESSION['my_guess'] = $_POST['guess'];
header('Location: great-number-game.php');
?>
