Well in fact it seams to be a cause of IIS server, implicit call of destructor is done before the end of the script

something like that :
class Object
{
  public function __construct()
  {
      ...
      ...
      echo 'end __construct';
  }
public function __destruct()
  {
      ...
      ...
      echo 'end __destruct';
  }
}
echo 'Construct';
$obj = new Object();
echo 'Done';

Will result :

Construct
end __construct
end __destruct
Done

I tried this script on IIS Server and Apache Server both with PHP 5.0.4

On Apache right result but not on IIS

I wouldn't copy the source code from the first message, but I'll add that if you use
$p = & new t();
instead of
$p = new t();
everything is going like it was expected.
Hope my message is enought informative. It is very annoying problem.

After several minutes of testing I found out that destructor isn't invoked (after creating an instance) if the constructer has parameters. So without parameters the destructor is invoked twice(first after creating, then after destruction the last link).
-------------------------------------
<?php
class t {	
	
	function __construct($new) {
		echo "constructor\n";		
	}

	function __destruct() {
		echo "destructor\n";
	}
}

$p = & new t($new);
?>
------------------------------------
//Out:
constructor
destructor
-------------------------------------
<?php
class t {	
	
	function __construct() {
		echo "constructor\n";		
	}

	function __destruct() {
		echo "destructor\n";
	}
}

$p = & new t($new);
?>
-------------------------------------
//Out:
constructor
destructor
destructor
-------------------------------------
So "& new t($new)" (param $new is requered) and parameters in definition of the constructor make it work right.
