Summary: Uninitialized ++$foo->bar; does not cause a notice
(but ++$bar; does!)
Status: Closed
Type: Bug
Package: Scripting Engine problem
Operating System: *
PHP Version: 5.*, 6
Assigned To: stas

New Comment:
The message is not consistent with the other one triggered in similar case.
Consider the following code:
$x = new stdClass();
echo $x->foo++;
echo $x->bar;
It triggers two notices:
Notice: Undefined property: foo
Notice: Undefined property: stdClass::$bar
The first one was added by fix for this bug and is wrong. It should be same as the other one (should
contain classname and dollar).

I think the fix is fine, but it may go only into 5.5 and above.

The problem here is that get_property_ptr_ptr does not produce notices. It doesn't
because it does not know the fetch type - in some cases it's BP_VAR_W, then it
shouldn't produce notice, in some it's BP_VAR_RW and then it should. However
get_property_ptr_ptr doesn't have a parameter to pass this info.
Looks like such parameter needs to be added...

I was talking about this:
http://svn.php.net/viewvc/php/php-src/trunk/Zend/zend_execute.c?revision=286362&view=markup#l251
With ++$foo, type is BP_VAR_RW, which makes sense and gives a notice. With ++$this->foo, it is
BP_VAR_W.
