Bug description: no access to error when extended class
Description:
------------
I know that this is a 'no no', but i feel that the bug here was not
bogus:
http://bugs.php.net/bug.php?id=37711
I disagree with the response. $this is used in the current class, whereas
parent:: is used to access properties and methods of the parent class.
errno and error are properties of the parent class, NOT of $this class.
Using $this to access the property of parent:: is not inheritance, it is
more closely related to symbiosis or polymorphism, or something. And
besides, how is parent:: automatically giving $this new properties called
errno and error? Shouldn't that only be done via a set/get type function?
EX:
function GetErrno(){
$this->errno=parent::errno;
}
function GetError(){
$this->error=parent::error;
}
The fact that this is automatically available in the scope of $this is NOT
inheritance, imho, it is a BUG.

Reproduce code:
---------------
class dbMYSQL extends mysqli {
...
function __construct(
parent::__construct($args....);
echo parent::errno;
echo parent::error;
}
...
}
Expected result:
----------------
0
''
or some error and error message when error occurs
Actual result:
--------------
Fatal error: Undefined class constant 'errno'
Fatal error: Undefined class constant 'error'
