Bug description: At least a notice when accessing private members in a derived class?
Description:
------------
Hi :)
I read in the new features list of Zend Engine 2 that access modifiers
like private/protected are introduced, but something really weird comes in
mind when reading carefully.
Private members are returned _empty_ wheing tried to be accessed from
derived classes. "Intended behaviour", is said. OK, i can live with that.
But even when i turned on notices with error_reporting, nothing is
noticed?
The case grows when looking at the following code sample. This could
produce very weird bugs when writing PHP code (i hope you can see that
;)), so I would like to convince you all to at least implement a Notice
when trying to access (non-defined) private (parent) members?
It would do the coders not using E_ALL no harm :) Please consider this :)
Reproduce code:
---------------
error_reporting ( E_ALL );
class Test {
private $member;
function __construct () { $this->member = "Test constructor"; }
function __toString () { return "Member contains:
{$this->member}"; }
function getMember () { return $this->member; }
function setMember ( $m ) { $this->member = $m; }
}
class DeriveTest extends Test {
function __construct () { parent::__construct (); }
function __toString () { return "Member contains:
{$this->member}, though getMember() says: " . $this->getMember() ."?"; }
function setMember ( $m ) { $this->member = $m; }
}
$o = new DeriveTest ();
echo $o, '<br>';
$o->setMember ( "a" );
echo $o, '<br>';
Expected result:
----------------
The expected result would be for me:
Notice: undefined member ``DeriveTest::$member'' in ...\test.php on line
12
Member contains: , though getMember() says: Test constructor?
Member contains: a, though getMember() says: Test constructor?
or something of the sort
Actual result:
--------------
The actual result is:
Member contains: , though getMember() says: Test constructor?
Member contains: a, though getMember() says: Test constructor?
