Bug description: Private instance variable visibile for new instance created within an object
Description:
------------
I found a situation which to me seems like unexpected behavior. I
private variable (as far as I know) should only be accessible within the
object itself, and not by the "outside world". Yet this becomes a bit
confusing once the object is created within an instance of itself. Is
this a bug or is this expected behavior?
Reproduce code:
---------------
<?
class Test{
private $variable = "asdf";
static function create_a_test(){
$tobj = new Test();
echo $tobj->variable; // Works! (which it shouldn't?!?)
}
}
$my_test = new Test();
//echo $my_test->variable; // Returns Fatal error: Cannot access private
property (which it should!)
$my_test->create_a_test();
?>
Expected result:
----------------
I would expect the above code NOT to return the private variable on line
7.
Actual result:
--------------
The private variable can be accessed without a problem.
