Code fails when viewed in IE 6.0 but works in Netscape 7.1???

[Phil Powell]

When I view the page (chat.php) in IE 6.0 the following code is
utilized:

[PHP]
if ($_COOKIE['val_chat']) {
// OPEN UP A NEW WINDOW TO SHOW THE CHATROOM
ob_start();
require_once("$ ABSOLUTE_MYCGIS ERVER_PATH/$PATH/chat_open_room. php");
$html .= ob_get_contents ();
ob_end_clean();
}
[/PHP]

Following is "chat_open_room .php":

[PHP]
<?
/*--------------------------------------------------------------------------

?>
<script>
<!--
var ie = (document.all) ? true : false;
var ne = (document.all) ? false : true;
var options = 'width=650,heig ht=420,toolbars =no,title=no,sc rollbars=auto,s tatus=no';
options += ',resizable=no, menubar=no,loca tion=no,directo ries=no';
if (ne) options += ',dependent=yes ';
chat = window.open('<? = $CHAT_ROOM_SELF ?>', 'Chatroom', options);
//-->
</script>
<noscript>
<!-- ADD LINK FOR NON-JAVASCRIPT USERS TO VIEW CHATROOM SINCE IT WON'T
JUST POP UP -->
<a href="<?= $CHAT_ROOM_SELF ?>" target=_new>Ope n Chatroom</a>
</noscript>
[/PHP]

In Netscape 7.1 I have absolutely no problems whatsoever with this
code resulting HTML; in IE, the browsers lock up into a runaway
process and I have to destroy all IE browser instances to free
resources to fix it.

If I comment out this line in chat_open_room. php:

[PHP]//chat = window.open('<? = $CHAT_ROOM_SELF ?>', 'Chatroom',
options);[/PHP]

Then I can see the problem: None of "chat_open_room .php" was ever
required at all! For some reason, there is nothing there. In
Netscape, everything is there. I am almost believing that server-side
code has now become client-dependent, which is impossible, of course,
but what is going on??
