Bug description:After destructor execution, object exists
Description:
------------
I think, in this example after destructor executing, object shouldn`t
exist. But result of this code tells something else...
Test script:
---------------
<?php
class A {
protected $var;
private static $instance = NULL;
public static function getInstance() {
if (is_null(self::$instance))
self::$instance = new A();
return self::$instance;
}
protected function __construct() {
echo "creating instance of A\n";
$this->var = "existing var in instance of A \n";
}
public function show() {
echo $this->var;
}
public function __destruct() {
echo "deleting instance of A\n";
}
}
class B {
private static $instance = NULL;
public static function getInstance() {
if (is_null(self::$instance))
self::$instance = new B();
return self::$instance;
}
protected function __construct() {
echo "creating instance of B\n";
}
public function __destruct() {
A::getInstance()->show();
echo "deleting instance of B\n";
}
}
header('Content-type: text/plain');
A::getInstance()->show();
B::getInstance();
?>
Expected result:
----------------
Some error?
Actual result:
--------------
creating instance of A
existing var in instance of A
creating instance of B
deleting instance of A
existing var in instance of A
deleting instance of B
