PHP Bug Type:     Scripting Engine problem
Bug description:  "return" returns a copy of an object instead of a reference

<?
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
