Upgraded from 5.2.3 to 5.2.4.
I could not find any reference to if (and why) it would change.
Changelog gives no clue either.
It happens to globally defined vars - php engine nulls the reference to
object before calling it's destructor. IMO illogical and inconsistent.
Worked fine before 5.2.4.

Upgraded from what PHP version..? AFAIK, this is how it should work, so
I don't understand why you report a bug about it..

Description:
------------
This is quite interesting. Appeared after upgrading to 5.2.4 and broke
my code.
It's great that objects are finally destroyed in the right order, but a
whole lot of code still relies on "destroy all" or "cleanup" functions.
What struck me is that as of 5.2.4, my object in the moment of calling
it's destructor, in global scope, appears as NULL.
I've also devised a simple and dirty workaround, which is found in the
code below.
Thanks!
Reproduce code:
---------------
class foo {
function __construct(){
echo "Constructed foo\n";
}
function getDb(){
echo "Getting DB";
}
function __destruct(){
echo "Destructing foo\n";
echo "Trying to destruct bar\n";
global $bar;
if(false){ // DIRTY WORKAROUND
global $foo;
$foo = $this;
}
$bar->__destruct();
}
}
class bar {
protected $destroyed = false;
function __construct(){
echo "Constructed bar\n";
}
function __destruct(){
if(!$this->destroyed){
echo " Destructing bar\n";
global $foo;
echo " Our global parent, foo, is of type
".gettype($foo)."\n";
$this->destroyed = true;
}
}
}
$bar = new bar();
$foo = new foo();
echo "--\nScript finishes...\n";
Expected result:
----------------
Constructed bar
Constructed foo
--
Script finishes...
Destructing foo
Trying to destruct bar
Destructing bar
Our global parent, foo, is of type object
Actual result:
--------------
Constructed bar
Constructed foo
--
Script finishes...
Destructing foo
Trying to destruct bar
Destructing bar
Our global parent, foo, is of type NULL
