Description:
------------
I have classes which do a var_dump as part of the __destruct() method
if the code is running from a the development domain (all the sites are
on the same server, live and development).

I recently turned on the zlib.output_compression in my php-isapi.ini
file.

This has been great for the live domains, but the development domains
generate no output.

If I toggle this setting and restart the webserver service (I am using
Sambar Server), then I get all the output I ask for.

The "Reproduce code" below proves my point.

It seems that the output stream is closed BEFORE the destruct() methods
are called, OR the destruct() methods generate output that bypassing the
zlib compression in some way.

I have also included the network trace logs relevant to the requests
from Sambar Server.

Sambar is not set to compress its output.




Reproduce code:
---------------
<?php
class MakeCommentWhenBeingDestroyed
        {
        private $bShowDestructionNotice = False;

        public function __construct($bShowDestructionNotice = False)
                {
                $this->bShowDestructionNotice = $bShowDestructionNotice;
                }

        public function __destruct()
                {
                if ($this->bShowDestructionNotice === True)
                        {
                        echo "We are being destroyed!";
                        }
                }
        }

$objMCWBD = new MakeCommentWhenBeingDestroyed(True);
echo 'Object created as <pre>' . var_export($objMCWBD, True) . '</pre>'
. date('r');
?>

Expected result:
----------------
Object created as 
class MakeCommentWhenBeingDestroyed {
  private $bShowDestructionNotice = true;
}
Mon, 08 Aug 2005 14:50:29 +0100We are being destroyed!

Valid tracelog from Sambar Server.
