2004-12-01: I fixed a couple of longstanding bugs:

  • the flash-of-unstyled-content plaguing users of internet explorer is now fixed.
  • uninitialized variables are no longer filling up the php error logs

NFG WebChat 1.1


NFGWebChat is a single channel chat webapplication written in pure PHP. It
was designed with two major goals in mind: Scalability and Accessibility. 

First and foremost it should be very stable under heavy loads. It will
easily take as many connections as your webserver will allow. Reduction of
disk IO to the absolute minimum was achieved by sharing a single PHP session
between all clients. I've done some simple benchmarking with ApacheBench
(ab), and the results were impressive.

The second design goal was accessibility. NFGWebChat strives to be useful
with all modern browsers without any kind of plugin. So, no java, no flash,
period. Only a single javascript element was added to improve usability, but
everything will work just fine without it. The only requirement (for now) is 
cookie support, and even that should be trivial to remove sometime. The result
is pure and validated XHTML1 and CSS2. For the visually impaired a frameless 
view is offered as well.


NFGWebChat is a stand-alone php webapplication. It doesn't require any other
code apart from PHP4 with session support. It does NOT work with PHP3. Just 
unpack the tarball somewhere under your DOCUMENT_ROOT, rename the directory
to some nifty cool name, and access it through any browser. If you want to
log the chat make sure the tmp directory is writable for the webserver.


You can edit style.css for the look-n-feel, and edit the templates to your
hearts desire. Just make sure you leave all the macros (%somevar%, etc) in
