Finally we need a way to get the troublemaker’s IP in
the first place. I do this by logging
and
URL I can view the message and monitor the IP
addresses at the same time. This has the added
bonus of being able to spot impersonators – a
common crime in these places.
the first place. I do this by logging
$nameand
$REMOTE_ADDR in a file callediplist.html. At a separate, secretURL I can view the message and monitor the IP
addresses at the same time. This has the added
bonus of being able to spot impersonators – a
common crime in these places.
iplist.html is created in much the sameway as
messages.html. First we extractthe current values from
iplist.html,we strip out the header, footer and oldest IP record
and then create a new record, new header and new
footer. To make the layout more clear, I used
a table.
<?php
$header
= "<html><body bgcolor="#000000" text="#ffffff"><table border="0">n";
$footer = "</table></body></html>";
$new_ip = "<tr><td>$name</td><td>$REMOTE_ADDR</td></tr>n";
$ip_array = file("iplist.html");
for ($counter = 1; $counter < 20; $counter++)
$old_ips.= $ip_array[$counter];
?>
Simply write that to the disk the same way as we
did the message file and there we have it. A simple
web-based chat room. Better cross platform
compatibility than Java and no need for anything
more than a web browser – I’m told that even the
Dreamcast
works with this!

Somethings you might want to try yourself include
combining common pieces of code into functions,
writing a script that will automatically add troublemakers
to the banned list and writing a regex expression
that scans a message text for URL’s and e-mail
addresses and automatically turning them into
likes (as Outlook Express and ICQ do).

Play around, have fun, experiment. I did. This is
how I started in PHP and now I’ve made a career of it.
Happy Chatting.
