Bug description: Child class cannot see protected member var from parent
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
