PHP - Passing variables from one page to another

Question

I am trying to pass on the value of one variable from one PHP page to another PHP page, but for some reason, it's not working..

Here's my code for phpOne.php:

<?php
    $x = 100;
    $_SESSION['sessionVar'] = $x;
    echo "$x";
?>

And here's my code for phpTwo.php:

<?php
$x = $_SESSION['sessionVar'];
echo "$x";
?>

Thanks in-advance! Tom!

You need to call session_start(); on both pages.
