Description:
------------
Hello,..
today I tried the code which I post as reproduce code. I expect in public_func2() the property which is declared as protected in the base class to be visible. However PHP bails out with message :
PHP Fatal error:  Cannot access protected property base::$a in /home/andrey/test/t.php on line 16 . Use of parent:: does not help also.
AFAIK protected member vars should be visible in the generalization classes.

As a side note please refer to bug #18024, for an additional effect which can be seen when using the reproduce code - shadowing of the variable declared in the base class. Method public_func1() of the base class uses the variable $a of "child" which is shadowing $a of "base". Is this an expected behaviour?

Thanks


Reproduce code:
---------------
<?php
class base {
        protected $a = array();

        public function public_func1() {
                var_dump($this->a);
        }
}

class child extends base {
        public $a = 2;

        public function public_func2() {
                var_dump($this->a);
                var_dump(parent::$a);
        }
}

$a = new child();
$a->public_func1();
$a->public_func2();
?>

Expected result:
----------------
int(2)
int(2)
array(0) {
}


Actual result:
--------------
int(2)
int(2)
PHP Fatal error:  Cannot access protected property base::$a in /home/andrey/test/t.php on line 16
