Some types of data can not be serialized thus stored in sessions. It
includes resource variables or objects with circular references (i.e.
objects which passes a reference to itself to another object).

This is absurd. There shouldn't be any reason I can't send a reference to
maybe it's more absurd to try a stick DOM XML objects into the
session in the first place?
another object -- Especially a built in type! UGH.
really why is that?
by all means write a patch that allows the serialization code
to serialize circular references. Though I imagine that it's
a little more difficult than it sounds.
then again you have __sleep() and __wakeup() magic methods which you
maybe able to use to 'shutdown' any references and 'bring them up' again.
btw I believe that the serialization code doesn't care whether objects
are 'built in' or not. it's purely a reference issue.

Subject: [PHP] PHP5, $_SESSION, DOM XML objects not returning value
I'm trying to store an array of DOM XML objects
(http://www.php.net/manual/en/ref.dom.php) in a PHP5.0.3
$_SESSION array,
but when I load the session back (and yes, I've declared my
class before the
session_start()), I get these errors:
Warning: XMLRule::getValue() [function.getValue]: Invalid State Error
in /lockdown/includes/classes/rule_xml.class.php on line 74
Or
Warning: XMLRule::getValue() [function.getValue]: Invalid State Error
in /lockdown/includes/classes/rule_xml.class.php on line 81
And all the VALUES are empty, however *my* XMLRule class
array seems right
otherwise. It's like PHP didn't serialize all of it's own DOM
XML objects
(which are built in objects!!!)
Here are the pertinent parts of the classes and other code snippets.

class XMLRule
{
// for example 'is_username' XML tag would set $name =
'Username'
protected $name = null;
// The reference pointer to the DOMNode, this is a wealth of
information in itself.
// look at the DOMNode class @
http://www.php.net/manual/en/ref.dom.php
protected $DOMNode = null;
protected function __construct($DOMNode, $name, $id = null)
{
$this-DOMNode = $DOMNode;
$this-name = $name;
$this-id = $id;
} //__construct()
function getValue()
{
//check for multiple values, such as a list of
names perhaps
[#74] if ($this-DOMNode-childNodes-length 1)
{
foreach ($this-DOMNode-childNodes as
$tmpNode)
$tmpArray[] = $tmpNode-nodeValue;
return $tmpArray;
}
else
[#81] return $this-DOMNode-nodeValue;
}

class is_username extends XMLRule
{
function __construct($DOMNode, $id = null) {
parent::__construct($DOMNode, 'Username', $id); }
}
class is_day extends XMLRule
{
function __construct($DOMNode, $id = null) {
parent::__construct($DOMNode, 'Day', $id); }
}
...etc...

require_once('classes/rule_xml.class.php');
if (!isset($_SESSION['ruleArray']))
{
$XMLDOC = new DOMDocument();
$XMLDOC-loadXML($xmlstring);
$ruleArray = array();
$i = 1;
$or = 1;
foreach($XMLDOC-firstChild-childNodes as $myNode)
{
if ($myNode-nodeName == 'and_conditions')

foreach($myNode-childNodes as $cNode)
{
$key = (string)($cNode-nodeName);

class
$ruleArray[$or][$i] = new
$key($cNode, $i);
$i++;
}
$or++; //begin new OR block
} //if and_conditions
} //foreach $myNode
$_SESSION['ruleArray'] = serialize($ruleArray);
}
else $ruleArray = unserialize($_SESSION['ruleArray']);
I've tried this with the un/serialize and without. PHP5 is supposed to
handle that for me, but just in case, I tried it anyways.
If I don't use the $SESSION, then things work fine and I have
my values.
I also tried to do this:
$_SESSION['ruleArray'] = $ruleArray;
$ruleArray = $_SESSION['ruleArray'];
And surprisingly that works (although it doesn't solve my problem).

Upon loading this back, this is what the array looks like in
either case
(working or not)
Array
(
[1] = Array
(
[1] = is_username Object
(
[name:protected] = Username
[DOMNode:protected] = DOMElement Object
