That's what the list is for... to help him find his way.

There are two approaches. You either are looking to do it as a
standalone application outside of the web environment, or you are
looking to do it via the web environment using some combination of
backend PHP and front end browser refreshes (not recommended) or AJAX.
A simple scenario for the web version follows:
1. User logs in (or implicitly is logged in anonymously)
2. User sees any ongoing discussion for X amount of previous time
3. User can post a form to the website (or post data via AJAX)
which effectively is the user's message to the chat server
4. Message is save to database with ID/timestamp
5. Browser refreshes or AJAX retrieves messages greater than
user's session message ID
6. Return to step 1.
The session is responsible for tracking the last message ID retrieved by
the user. This could also be facilitated by the browser, but it will
almost certainly be problematic. Additionally, but having it in the
session you ensure the user can't arbitrarily jump back in time (this
may be a privacy issue if chat users only expect those logged in to ever
see their messages). Additionally when saving messages or viewing
messages you may want to track a group ID that refers to the chat forum
in which the messages are being posted/retrieved. In this way you can
have multiple chat rooms.
This should get you started or asking questions more to the point.
Cheers,
Rob.

Should have been:
6. Return to step 3.

Robert, Abderrazzak,
You make some good points, and apologies abderrazzak; I woke under
stress and haven't been the friendliest today!
The Ajax method is definately a good approach, particulary if you're
wanting to have the chat client within a web page.
The other approach is to make a php chat daemon, this can be achieved by
running php through the CLI. To get started some reading of the PHP
Manual would be advised, partculary under stream_socket_server,
stream_socket_accept, pcntl_fork, the CLI section itself, and finally
some catching up on php wrapeprs to stdin, stdout and stderr -
stream_socket_pair may come in useful aswell.
I'd strongly recommend you follow Roberts advice to start with, and
build that chat application as a standrd php app with mysql and an ajax
front end (perhaps even an iframe whilst developing functionality, then
upgrade to ajax).
Many Regards
Nathan

then I got three solutions for you, either make a (as mentioned by others on
the list) an ajax frontend witch do the irc lookalike.
You can create a webinterface for an irc server. I think java is often used
for this solution, you can probably also use ajax. (this isn't as hard as is
looks, I think this solution is easier than the first one)
And as a third and ... the COOL solution is to user the jabber 2.0 as the
backend and some php stuff in the middle and a nice interface, that you can
connect directly using a jabber client (maby throught a mobile) and someone
on the same time using the webpage to chat with you ?;D This option is of
course available on the second option to, except you use irc.
All this open protocolls just makes us nerds go crazy!!!

Hey folks,
One area I lack experience in is writting a solution to index/search on a
site. Would anyone be kind enough and point me in the right direction as far
as any books which discuss some simple solutions or articles/blogs on the
web? Clearly I'm not looking for anything as complex as Google's engine, ;-)
but would love just to be able to understand/incorporate a decent level of
search capabilities.
Cheers all,
- sf

Hello,
This is quite simple, you need to have mysql table with "fulltext" index.
The "hard work" is done by mysql, you need to learn a few of things
about fulltext with mysql, for that you can google it.
PHP is only used to send the query to mysql (in most of case but not always).
Try to do something, and when you need help, only ask here...
good luck :)
