Bug description: Problem with extending classes
Description:
------------
I want to extend a class C from another class class B who was extend
from my abstract class A. I want to get the different value of the same
variable. So I initialize my variable "name" and read the variable at
my function "__toString()", so please look to my code couse my english
is not the best ;) . its hard for me to explain.
Reproduce code:
---------------
abstract class A {
public $name = "CLASS:A";
public function __toString(){
return " => ABSTRACT " . $this->name;
}
}
class B extends A {
public function __construct(){
$this->name = "CLASS:B";
}
public function __toString(){
return " => " . $this->name . parent::__toString();
}
}
class C extends B {
public function __construct(){
parent::__construct();
$this->name = "CLASS:C";
}
}
$deb_b = new B();
$deb_c = new C();
printf("Result: Beginn B %s<br />", $deb_b);
printf("Result: Beginn C %s<br />", $deb_c);
Expected result:
----------------
Result: Beginn B = => CLASS:B => ABSTRACT CLASS:B
Result: Beginn C = => CLASS:C => ABSTRACT CLASS:C
Actual result:
--------------
Result: Beginn B => CLASS:B => ABSTRACT CLASS:A
Result: Beginn C => CLASS:C => CLASS:B => ABSTRACT CLASS:A
