session_regenerate_id() works to regenerate the session by replacing oldsessionid.
For this, first start the session,
set the sessionid equal to oldsessionid and print oldsessionid.
Now use the session_regenrateid and set this id to new sessionid.
<?php
session_start();
print_r($_SESSION);
echo "<br />";
$oldsessionid = session_id();
echo "Old Session:". $oldsessionid."<br />";
session_regenerate_id();
$newsessionid = session_id();
echo "New Session:". $newsessionid."<br />";
?>
