Bug description: refcount is not updated
Description:
------------
I'd like use '=null' on variables who points to object.
but the refcount is not updated in this case.
It is updated only after unset on variable.
is it a real pb ?
By,
Reproduce code:
---------------
a small test ->
class a{
}
class b extends a{
}
class t{
var $r = null;
var $pr = null;
function test(){
$this->r = &new b();
echo "nb Ref r apres new = " . pars_infoo($this->r);
$this->pr = &$this->r;
echo "<br/>nb Ref pr apres pr = " . pars_infoo($this->r);
echo "<br/>nb Ref r apres pr = " . pars_infoo($this->pr);
//unset($this->pr); OK
$this->pr = null;
echo "<br/> nb Ref r apres unset " . pars_infoo($this->r);
}
}
$b= new t();
$b->test();
source for pars_infoo(Zend)
if ((*pO)->is_ref)
ret = strUWFormat(ret, nPos, &nPos, "nb référence = %hd",
(*pO)->refcount);
Expected result:
----------------
if i make unset it's ok
->
nb Ref r apres unset nb référence = 2 <- ok
Actual result:
--------------
->
nb Ref r apres new = nb référence = 2
nb Ref pr apres pr = nb référence = 3
nb Ref r apres pr = nb référence = 3
nb Ref r apres unset nb référence = 3 <- wrong
