Nope.
The output is ...
destroy A destroy B
Objects are destroyed in the order they are created. This is, in my
opinion, bad.
I would expect ...
destroy B destroy A
(and it took me at least 2 minutes to work out why I got nothing at all
- short tags!).

Please, run this code:
<?
class a {
function __destruct() {
echo "destroy A\n";
}
}
class b {
function __destruct() {
echo "destroy B\n";
}
}
$a = new a;
$b = new b;
?>
and make sure that it works as you expect.

Description:
------------
Hi.
Create Object A (a action logging class)
Create Object B (a class which allows generates logging actions).
As each method in B is called a log entry is made by using an IN and
OUT method on A.
During the shutdown, the __destroy method of A is called (which closes
the log), then, the __destroy method of B is called. This method has
the logging code in it. This then tries to call a destroyed object.
As you cannot refer to an object until it is created, you should always
destroy objects in the reverse order in which they were created.
Richard.
Reproduce code:
---------------
<?php
class A
{
public function __construct()
{
echo 'Constructing A<br />';
}
public function __destruct()
{
echo 'Destroying A<br />';
}
public function Logging($sLog)
{
echo date('r') . ' '. $sLog . '<br />';
}
}
class B
{
public function __construct()
{
$GLOBALS['objLogger']->Logging(__METHOD__ . ' ' . __FILE__ . '
' .
__LINE__);
}
public function __destruct()
{
$GLOBALS['objLogger']->Logging(__METHOD__ . ' ' . __FILE__ . '
' .
__LINE__);
}
public function Action()
{
$GLOBALS['objLogger']->Logging(__METHOD__ . ' ' . __FILE__ . '
' .
__LINE__);
}
}
$objLogger = new A();
$objAction = new B();
$objAction->Action();
?>
Expected result:
----------------
Constructing A
