PHP Session variables dissapear with header redirect

Question

My session variables are empty when I login users and use a header redirect.

/* Login page */
session_register("myusername");
session_register("mypassword");

$_SESSION['myusername'] = $_POST['myusername'];

header("location:page.php");

/* page.php */

<?php echo $_SESSION[myusername]; ?>

session_register function has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 5.4.0. — Dr. Dan

You should not use session_register function when you use $_SESSION superglobal array and you did not start your session. Try

/* Login page */
session_start();

$_SESSION['myusername'] = $_POST['myusername'];

header("location:page.php");

/* page.php */

session_start();

<?php echo $_SESSION[myusername]; ?>

Did you include session_start() call at the start of the script page?,that is the most common issue i'm aware of with sessions in php.
