Just as kudose answered. Say in your first page in the form you have two fields, one named test and the other test2. What you want to do is set the form action to post, then on the page that it gets redirected to include this at the top.
<?
$test = $_POST ['test'];
$test2 = $_POST ['test2'];
?>
Then anywhere in the page that you want to display those values, use this:
<?
echo "$test";
echo "$test2";
?>
