Don't use $this to pass a reference to the current object in the object's constructor.
class parent
{
var $child;
function parent()
{
$this->child = new child(&$this);
}
}
class child
{
var $parent;
function child(&$parent)
{
$this->parent = &$parent;
}
}
$parent = new parent();
for some reason
$parent != $parent->child->parent
if you need to pass a reference to child objects, use eg. an init-function, in which &$this will
work just fine. Just don't use the constructor.
