hi all , I have to system running Ubuntu 13.04 . on my laptop everything works fine but on my PC I can not work with session variable , I have installed Apache2 and PHP from terminal ,i'm running a same code on both devices.
the code that I used for checking if the variable is set or not on every page is :
<?php
session_start();
if(!isset($_SESSION["mys"]))
{
header('location:../index.php');
}
?>
as you can see if the variable do not set , user would redirect to the index page .
the problem is my session variable is not getting set at all , this is a code that i ran on both devices :
<?php
session_start();
?>
