Passing Objects Via Session in PHP 4

[Joseph Crawford <codebowl@xxxxxxxxx>]

can anyone explain why this is not working?  i have done passing
objects via session before and i remember that the object class file
had to be included before the session_start for it to work, but this
doesnt seem to be working, i mean i have it set $db->test = 'page 1';
on page 1 and provide a link to page 2, but it doesnt seem to retain
the value for $test from page to page. :(

<?php

// we will do our own error handling
error_reporting(0);

// include the const.php file that holds all the necessary constants
include_once('const.php');

include_once('class/mysql.class.php');
include_once('class/template.class.php');

session_start();

function &getObject($class) {
	if (!isset($_SESSION['objects'])) {
		$_SESSION['objects'] = array();
	}

	if (!isset($_SESSION['_singleton'][$class])) {
		$_SESSION['objects'][$class] =& new $class;
	}

	return $_SESSION['objects'][$class];
}

$tpl = &getObject('template');

// user defined error handling function
// taken from the example on http://us2.php.net/errorfunc
function myErrorHandler($errno, $errmsg, $filename, $linenum, $vars)
{
	global $tpl;
	// timestamp for the error entry
	$dt = date("Y-m-d H:i:s (T)");

	// define an assoc array of error string
	// in reality the only entries we should
	// consider are E_WARNING, E_NOTICE, E_USER_ERROR,
	// E_USER_WARNING and E_USER_NOTICE
	$errortype = array (
	E_ERROR          => "Error",
	E_WARNING        => "Warning",
	E_PARSE          => "Parsing Error",
	E_NOTICE          => "Notice",
	E_CORE_ERROR      => "Core Error",
	E_CORE_WARNING    => "Core Warning",
	E_COMPILE_ERROR  => "Compile Error",
	E_COMPILE_WARNING => "Compile Warning",
	E_USER_ERROR      => "User Error",
	E_USER_WARNING    => "User Warning",
	E_USER_NOTICE    => "User Notice",
	E_STRICT          => "Runtime Notice"
	);
	// set of errors for which a var trace will be saved
	$user_errors = array(E_USER_ERROR, E_USER_WARNING, E_USER_NOTICE);

	$err = "<errorentry>\n";
	$err .= "\t<datetime>" . $dt . "</datetime>\n";
	$err .= "\t<errornum>" . $errno . "</errornum>\n";
	$err .= "\t<errortype>" . $errortype[$errno] . "</errortype>\n";
	$err .= "\t<errormsg>" . $errmsg . "</errormsg>\n";
	$err .= "\t<scriptname>" . $filename . "</scriptname>\n";
	$err .= "\t<scriptlinenum>" . $linenum . "</scriptlinenum>\n";

	if (in_array($errno, $user_errors)) {
		$err .= "\t<vartrace>" . wddx_serialize_value($vars, "Variables") .
"</vartrace>\n";
	}
	$err .= "</errorentry>\n\n";

	// for testing
	// echo $err;

	// save to the error log, and e-mail me if there is a critical user error
	error_log($err, 3, "D:/htdocs/NYPHPCode/error.log");
	if ($errno == E_USER_ERROR) {
		mail("jcrawford@xxxxxxxxxxxx", "Critical User Error", $err);
		$tpl->display('error.tpl');
	}
}
$old_error_handler = set_error_handler("myErrorHandler");
