Sessions and Objects using PHP4

[David OBrien <dgobrien@xxxxxxx>]

I have RTFM and TTFE and still am having a heck of a time getting my 
objects to play well between pages
The only real examples are in the notes for classes & objects
http://us2.php.net/manual/en/language.oop.php

Basic usage
<?
include_once("config.inc");
include_once("class.php");
$songbook = new songbook(); // defined in the class.php
session_register('songbook');
$songbook->get_stats();
$songbook->populate_manu();
$songbook->populate_series();
if (!isset($songbook->userid) || $songbook->userid == "") {
	header("Location: login.php");
}

Now the login.php is basically the same but if the login correctly it 
should set $songbook->userid to the username

require('common.php');
session_start();
include_once("class.php");
$songbook = new songbook();
session_register('songbook');
include("newheader.php");
if ( isset($_POST['submitit'])) {
	$link = dbconnector();
	$sql = "select * from userinfo where 
lower(username)=lower('".$_POST['user']."') and 
lower(password)=lower('".$_POST['pass']."')";
	$result = mysql_query($sql);
	if( mysql_num_rows($result) > 0 ) {
		$songbook->userid = strtolower($_POST['user']);
		header("Location: green.php");
	} else {
		$errormsg = "<font size=3>Invalid Username or Password.<br>\nPlease Try 
Again.</font>";
	}
}

So I guess what I am asking is how DO you make objects work across pages?
