class Node
{
	var $name;
	var $next;

	function Node($name)
	{
		$this->name = $name;
		$this->next = NULL;
	}

	function getNext()
	{
		return $this->next;
	}

	function setNext($next)
	{
		$this->next = $next;
	}
}

$head = new Node("david");
$curr = $head;
$curr->setNext(new Node("peter"));
$curr = $curr->getNext();
$curr->setNext(new Node("john"));

$curr = $head;
while ($curr)
{
	print("<p>".$curr->name."</p>");
	$curr = $curr->getNext();
}

The problem with the code above is.. only "david" is printed.. why isn't the rest of the Nodes printed ?
I have checked the linkage
If seems like $curr->next is NULL instead of the next Node in the linkedlist... What have I did wrongly ?
