php.net has probably the best information on this subject.
Briefly, you place information in a session like so:
$_SESSION['variable_name_here'] = "foo";
This session will remain until the user logs off or until you destroy
it.
You then access it just like you would any other variable.
$bar = $_SESSION['variable_name_here'];
echo $bar;
// prints 'foo'
