New Comment:

renaming the function:

function AddChild(...


function &AddChild(...
makes return return by reference instead of by value, i didnt think to do this so it 
appears its my fault:)

i've changed this bug to a documentation problem tho cos i cant find any reference to 
this in the docs.

Class ChildClass {
        var $value;
        function ChildClass($value){
                $this->value = $value;

Class ParentClass {
        var $children;
        function ParentClass(){
                $this->children = array();
        function AddChild($value){
                $child = &new ChildClass($value);
                array_push($this->children, &$child);
                return $child;

$p1 = &new ParentClass();

$c1 = &$p1->AddChild('set in constructor');
$c1->value = 'set elsewhere';

echo "the reference to the object created in AddBand and stored in the parentclass' 
array is different to that returned by the AddBand function<br>";
echo $p1->children[0]->value."<br>";
echo $c1->value;


"return" is returning a copy of the object created in parentclass->AddChild instead of 
a reference. "return &$object" is flagged as invalid by the php interpreter.

thanks a lot
