Session is unable to store an array of classes. If you try to add to an array (using []) stored in the session, it overrides the array instead of adding to it

Here's a sample code:


<?
include_once("cls1.php");
if (!session_is_registered("ClassOne")) {
	session_register("ClassOne");
	echo "<BR>ClassOne now in session";
}
?>
<BR><B>Right now we have <?= sizeof($HTTP_SESSION_VARS["ClassOne"])?> classes</B>.<P>
<?
if ($HTTP_GET_VARS["count"] != 0) {
	for ($i = 0; $i < $HTTP_GET_VARS["count"]; $i++) {
		$HTTP_SESSION_VARS["ClassOne"][] = new ClassOne(); //this line should add to the array
	}	
}

?>
<B>And now we have <?= sizeof($HTTP_SESSION_VARS["ClassOne"])?> classes</B>.<P>

<form method="get" action="regcls.php">
Register <input type="text" name="count" size="3"> objects.
<input type="submit">
</form>
<PRE>
<?
if ($HTTP_GET_VARS["delete"] == 1) {
	
	echo "<BR>Killing CountOne from session...";

	$HTTP_SESSION_VARS["CountOne"]=0;
	session_unregister("CountOne");

}
for ($i=0; $i < sizeof($HTTP_SESSION_VARS["ClassOne"]); $i++) {
	echo "\n$i ClassOne->count = ". $HTTP_SESSION_VARS["ClassOne"][$i]->getCount();
}
?>
</PRE>
<?
