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
