[PHP-DEV] Re: About bug #26182..(Object properties created redundantly)

[Andi Gutmans]

I commited a fix. I am not quite sure why the existing code was doing what 
it was so I'm waiting for Zeev (who wrote that part) to verify that my fix 
is OK. (He's travelling right now so it'll take some time).
In the meanwhile, if any of your scripts break because of my fix please let 
me know.

    This script:

                if(isset($this->x)){
                        //just for demo
                }
        }
}
$t=new A();
var_dump($t);
?>

    Output with php4:

object(a)(0) {
}
    Output with php5:

object(a)#1 (1) {
  ["x"]=>
  NULL
}
    The property x gets created by that check if it exists in the class..
    Pretty high WTF factor IMO. And someone might rely that a property STAYS
    unset even if they happen to check it in their methods.
