Description:
------------
When using PHP 4.3.7, foreach() will produce error messages when glob() returns false. However, it will still function. The error message is very unsightly.


Download the script in question from http://piranhaweb.xgt.us/dl/zChat_1.4.zip

Note: The script works perfectly fine in previous versions of PHP.

Reproduce code:
---------------
http://www.familytables.net/chat

Expected result:
----------------
In the right-hand frame, where the error is mostly occuring, you will see (assuming nobody is in the chat room):

x Active Users
INVALID ARGUMENT FOR FOREACH() ERROR
name (y)
name (y)
...


Actual result:
--------------
1 Active Users
Error: Invalid argument supplied for foreach() in online.php
