Session variable unavailable in ajax handler ( php script )

Share corn :

My directory structure looks like below:

public_html
    |_ ajax
        |_ test_handler.php
    |_ test.php

My test.php looks like this:

session_start();
if(isset($_SESSION["tested"]) && $_SESSION["tested"] == "NO"){
    //unset the session array and destroy current session
    destroyActiveSession();

    //start a new session
    session_start();

    $_SESSION["test_var"] = "Hello world!"
    $_SESSION["tested"] = "YES"
}

test_handler.php has following code(simplified):

session_start();
exit($_SESSION["test_var"]);

Using local environment(XAMPP) and executing on google crome

In test.php page $_SESSION["test_var"] works fine but in test_handler.php I'm getting Undefined index: test_var error. What am I doing wrong???

So if anyone ran into this problem, here's what solved my problem: New test.php:

session_start();
if(isset($_SESSION["tested"]) && $_SESSION["tested"] == "NO"){

    //unset the session array 
    $_SESSION = array();

    $_SESSION["test_var"] = "Hello world!"
    $_SESSION["tested"] = "YES"
}

And new test_handler.php :

<?php
    session_start();
    exit( $_SESSION["test_var"] );
?>
