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 ?
