Class serialization with recursion

[Anon]

Hi,

I'm trying to make some universal PHP library, which will be object based (I was inspired by PML)

But I have problem with class serialization in session...

try this code (two-way list):

<?
class test {
var $child, $parent, $name;

function test($nm) {
	$this->name = $nm;
}

function registerchild($name) {
	$this->child = new test($name);
	$this->child->parent = & $this;
}

}

session_start();

if (!session_is_registered("main")) {
$main = new test("main");
$main->registerchild("childone");
$main->child->registerchild("childtwo");
$main->child->child->registerchild("childthree");

echo "first run"."<BR>";

}

$obj = & $main;
while (is_object($obj)) {
echo $obj->name."<BR>";
$obj = & $obj->child;
}

if (is_object($main)) {
echo "Main is object!<BR>";
}

$obj = & $main->child->child->child;
while (is_object($obj)) {
echo $obj->name."<BR>";
$obj = & $obj->parent;
}

session_register("main");
?>

The first run is OK, but the others are bad. Why??? Is it a bug or a feature (recursive classes forbidden)????

If you tell me, that I shouldn't pass whole class to session, it won't help me 🙂) But it seems that I should do it another way... (if nobody solves it)

Thanks

I'm sorry for my terrible english... If I understand well, the only trouble lies in the PHP syntax and the problem can be resolved by use of some additional variables. Something like this:

$main = new test("main");
$main->registerchild("childone");
$child1 = $main->child;
$child1->registerchild("childtwo");
$child2 = $child1->child;
$child2->registerchild("childthree");

...and so on :o)

Have a nice day.
