Bug description: Accessing overloaded member via foreach does not work
Description:
------------
Using an overloaded property from an object instance directly in a foreach
fails. If you assign the property (or a reference to it) to a variable
first it works fine. This is reproducable.
Interestingly enough, I see a strange problem with inheritance and
overloaded members. I am unable to reproduce it in a simple example. I
will continue to work that. Basically, you get the same fatal error as
here BUT on assignment to a member variable of the parent class that is
not overloaded. It's bizzare. As soon as I remove the __get/__set from the
child, the parent method works fine again from an instance of child. Again,
simple examples do not seem to reproduce. <sigh>
Reproduce code:
---------------
class Son
{
protected $m_aActions;
function __construct(&$aActions)
{
$this->m_aActions = $aActions;
}
function __get($mName)
{
$mRetval = null;
switch($mName)
{
case("Actions"):
{
$mRetval = $this->m_aActions;
break;
}
}
return $mRetval;
}
}
$aActions = array("add", "delete");
$oSon = new Son($aActions);
$aActions = $oSon->Actions;
var_dump($aActions);
foreach($oSon->Actions as $strAction)
{
echo $strAction . "\n";
}
Expected result:
----------------
array(2) {
[0]=>
string(3) "add"
[1]=>
string(6) "delete"
}
add
delete
Actual result:
--------------
array(2) {
[0]=>
string(3) "add"
[1]=>
string(6) "delete"
}
Fatal error: Cannot access undefined property for object with overloaded
property access
