Bug description: cannot pass result of __get by reference
Description:
------------
From outside a class, accessing a variable via a __get is identical to
accessing one via a public member:
$publ->varr
vs.
$gets->varr
When trying to pass by reference, I would expect the corresponding __set
to be called when the value originaly came from a __get. Instead, there is
a Fatal error.
Reproduce code:
---------------
class PublicVar {
public $varr;
}
class GetSetter {
protected $data = array();
function __get($key) {
return $this->data[$key];
}
function __set($key, $value) {
$this->data[$key] = $value;
}
}
function set_by_ref(&$variable) {
$variable = 'has been set, ';
}
$publ = new PublicVar();
set_by_ref($publ->varr);
echo $publ->varr;
$gets = new GetSetter();
set_by_ref($gets->varr);
echo $gets->varr;
Expected result:
----------------
has been set, has been set,
Actual result:
--------------
has been set
Fatal error: Cannot access undefined property for object with overloaded
property access in C:\eclipse\workspace\tmote\tmp_byref.php on line 27
