Bug description:incorrect private property handling in extended class
Description:
------------
test script $t->priv2 throws
Notice: Undefined property: test::$priv2 error.
Test script:
---------------
class base {
private $priv = "private";
protected $prot = "protected";
public $pub = "public";
final public function __get($prop){
$cv = get_class_vars(__CLASS__); $ccv =
get_class_vars(get_called_class());
var_dump('GET--------------', $prop, get_called_class(),
__CLASS__,
$this, $cv, $ccv, isset($this->$prop), property_exists($this, $prop));
return $this->$prop;
}
final public function __set($prop, $value){
$cv = get_class_vars(__CLASS__); $ccv =
get_class_vars(get_called_class());
var_dump('SET--------------', $prop, get_called_class(),
__CLASS__,
$this, $cv, $ccv, isset($this->$prop), property_exists($this, $prop));
$this->$prop = $value;
}
}
class test extends base {
private $priv2 = "private";
protected $prot2 = "protected";
public $pub2 = "public";
}
// pub2 and prot2 works.
$t = new test();
echo $t->pub2; echo $t->prot2; echo $t->priv2;
Expected result:
----------------
like base class results:
// it works.
$b = new base();
echo $b->pub; echo $b->prot; echo $b->priv;
Actual result:
--------------
Inconsistent behaviour:
1) $this has 6 properties (pub, prot, priv, pub2, prot2, priv2): good
2) get_class_vars(get_called_class()) has 5, priv2 missing: wrong
3) isset($this->$prop) returns false in this case: wrong
4) property_exists($this, $prop)) returns true: good
