Object Reference in a class

[gangclar]

I've a confusing issue here...

class A
{
var $ID;

function GetID() { return $this->ID; }
function PutID($newID) { $this->ID=$newID; }
}

Class B
{
var $ObjA;

function B() { $this->ObjA=new A; }
function &GetObjA() { return $this->ObjA; }
}

$First=new B();
$ObjA=&$First->GetObjA();
$ObjA->PutID("Testing");

$Obj=&First->GetObjA();
echo $Obj->GetID();

It seems that blank is returned, meaning that the method PutID() didn't seems to set the value in object First.

Any clue?
Thanks!

instead of this:

function &GetObjA() { return $this->ObjA; }

do this:

function &GetObjA()
{
$temp = &$this->ObjA;
return $temp;
}

You'll have to do the same to be able to call any properties of the sub-object.
