#36487 [NEW]: object === same object mismatch

[Php - GTK - Dev mailing list]

From:             xxoes at nw7 dot de
Operating system: windows & linux
PHP version:      5.1.2
PHP Bug Type:     PHP-GTK related
Bug description:  object === same object mismatch

Description:
------------
Although the objects have the same object id after destruction, "==="
doesn't equal them any more.

I try:
   $abc = new abc();
   $obj = new bla();
and:
   $abc = new abc();
   $obj = new bla();

both the same result.

This does not happen when you remove "extends GtkObject" from the class
signature.

Reproduce code:
---------------
<?PHP
   class bla extends GtkObject {
      public $xparent;

      function __construct() {
      }

      function __destruct() {
         echo "bla::__destruct()\r\n";
         $this->xparent->remove($this);
      }
   }

   class abc {
      function __destruct() {
         echo "abc::__destruct()\r\n";
      }

      function put($obj) {
         $this->obj = $obj;
         $obj->xparent = $this;
      }

      function remove($obj) {
         echo "Object matched?: ".($this->obj === $obj)."\r\n";
         echo $this->obj." ".$obj."\r\n";
      }
   }

   $abc = new abc();
   $obj = new bla();
   $abc->put($obj);
?>

Expected result:
----------------
That the operation $this->obj === $obj is true.

Actual result:
--------------
$this->obj and $obj mismatch.

I don't think this is PHP-GTK related. If you replace GtkObject with
DOMElement you get the same result. Double check the general PHP bugs
and if it hasn't been reported yet, you should switch this over to a
regular PHP bug.

As far as I see that, the objects *are* identical.
They equal === as long as they are not in the process of being
destroyed - but as soon as the destroying process is begun, they don't
equal any more although they are still equal

Sorry but i don't understand!

Thats are the same objects and the same instances, and === doesn't
matched!

It works fine if a call $obj->__destruct === is true, but not if this
function is called by php on exit.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

For === to return true on object comparison both objects must be
instances of the same class and refer to the exact same internal
object.

No isn't php-gtk related. Is a general problem because DOMElement and
GtkObject have the same result.

The order that objects are destroyed in cannot be guaranteed, so it's
generally a good idea not to be trying to fiddle with objects (even
objects stored inside other objects) in destructors
