Bug description: "Undefined property" notice when accessing property in __get
and __set
Description:
------------
If you have a child class that inherits from a parent class that
implements __get and __set and you access a private property from within
these functions, then you will get a notice "Undefined property" when
trying to access this property from an instance of the child class. If you
try accessing the properties from an instance of the parent class, it works
as expected.
Reproduce code:
---------------
class ParentClass
{
private $parentMessage = "Hello, from parent!";
private function __get($property)
{
echo "__get($$property)\n";
return $this->$property;
}
private function __set($property, $value)
{
echo "__set($$property, $value)\n";
$this->$property = $value;
}
}
class ChildClass extends ParentClass
{
private $childMessage = "Hello, from child!";
}
$parent = new ParentClass();
echo $parent->parentMessage . "\n";
$child = new ChildClass();
echo $child->childMessage . "\n";
Expected result:
----------------
__get($parentMessage)
Hello, from parent!
__get($childMessage)
Hello, from child!
Actual result:
--------------
__get($parentMessage)
Hello, from parent!
__get($childMessage)
Notice: Undefined property: ChildClass::$childMessage in C:\www\bug.php
