Can't read session vars passed to script

[magician]

Hi I've got problem with reading session vars that were passed into another PHP script. That's how my files look like:

[start.php]

<?php
session_start();
$var="data123";
session_register('var');
?>
<a href="second.php">Link</a>

[second.php]

<?php
global $var;
print $var;
?>

After click on the link my (second.php) script print nothing. What's wrong?

global $var; // is it necessary at all

use session_start(); in second.php, too.

this function has to be called in every script which uses sessoin vars.

session_register('var') on the second page as well.

I'd also recommend session-registering $var before setting its value, too. If $var already happens to have a sessioned value from a previous page, it will overwrite the 'data123'. Unless that's the behaviour you want, of course.
