PHP IRC Bot Class

[kettle_drum]

Heres a class to deal with an IRC bot. It can do quite a lot of things, such as:

-op/deop/voice/devoice/kick users
-set channel topic/mode
-google searches
-weather checks for US zip codes
-magic 8ball
-get bash.org quotes
-add/view user submitted quotes
-give current time of a given time zone
-read a file to a channel in the style of a lecture
-various encryption - base64/rot13/md5
-Controls user control by names in a database

I know its a bit bigger than just a code snippet - but i thought some people may find it useful or simply just interesting. Hope you enjoy!!

Also maybe some people could give me some types on refining my code, or faster methods to do things etc etc. just general "heres how you can improve you coding" types of comments. Thanks

The class - ak_bot.php

Code: Select all

Heres the code to call the bot class:
bot.php

Code: Select all

 
<?php
   include("ak_bot.php");
 
   $bot[log] = 1;
 
   $bot[botnick] = "Ak-Void";
   $bot[botpassword] = "password";
   $bot[botident] = "Ak-Void";
   $bot[botrealname] = "Advanced Knowledge Void";
   $bot[localhost] = "localhost";
 
   $bot[serveraddress] = "irc.server.com";
   $bot[serverport] = "6667";
   $bot[serverchannel] = "#macwhore";
 
   $bot[database_host] = "localhost";
   $bot[database_user] = "user";
   $bot[database_password] = "thisismypassword";
   $bot[database_name] = "akbot";
 
   $mybot = new AK_Bot($bot);
?>
 

Then you will need the following sql:

Code: Select all

 
#holds access details to the bots controls
CREATE TABLE access (
  user varchar(20) NOT NULL,
  level tinyint(1) NOT NULL DEFAULT '1',
  channel varchar(255) NOT NULL,
  server varchar(255) NOT NULL
);
 
#holds quotes
CREATE TABLE quote (
  id int(8) NOT NULL AUTO_INCREMENT,
  added_by varchar(20) NOT NULL,
  quote text NOT NULL,
  time_posted int(10) NOT NULL,
  PRIMARY KEY(id)
);

That's interesting - not something I've ever tried to do before.

One comment: I wondered if it would be good to refactor it into a bunch of objects rather than one single class. Db conn, for example, probably shouldn't be in an IRC bot class.

Maybe it's a question of personal style to a certain extent but I always try to refactor methods & classes ruthlessly down to the bone. Lots of unexpected and pleasant surprises can come out of that.

[kettle_drum]

Yeah i guess dividing up the functions into more refined objects would be a good idea. I could then also remove the bot actions into a seperate class, and be left with a pure IRC class that would deal with connecting, disconnecting, sending and recieving data.

[KrisH]

nice code br0, one little question is this an example of makeing a bot go into a network and a specfic channel? if so.. it's pretty cool, i know alot of host that give free sql and php... this can be an exploit if i may say for using free host as a mirc bot? reply to me if i am wrong, i am not farmilur with your code, sorry for my bad english also

[Roja]

Once you've called the bot, and its connected, what keeps it active? Ie, why does it remain on the channel, and keep the connection open?

I would have thought that the connection would timeout after some period of time if the calling program didnt continue to communicate with it.

[ol4pr0]

Havents looked at the complete script, however i am kinda a oldtimer on the networks of irc.

Regarding youre question on what keeps it alive. ( a ping )

when the nick / b0t gets ping timedout it will be kicked of the network of just simply disconnect itself.

However i do suggest you use a BNC for running b0ts. I do not know youre connection or the network youre on, however if you do have a pretty nice channel lets say over 400 p33ps youre b0t is bound to be attacked.

[Roja]

Havents looked at the complete script, however i am kinda a oldtimer on the networks of irc.

Same here.

Regarding youre question on what keeps it alive. ( a ping )

I don't see a persistent connection, nor a regularly-scheduled ping in the bot class posted. Did I miss it?

when the nick / b0t gets ping timedout it will be kicked of the network of just simply disconnect itself.

Right - without constant reconnects/pings/activity it will lose connection. So what keeps this bot online?

However i do suggest you use a BNC for running b0ts. I do not know youre connection or the network youre on, however if you do have a pretty nice channel lets say over 400 p33ps youre b0t is bound to be attacked.

Well sure - but the concept here is a php-written BOT, or is it? If it is, I am very unclear about how it STAYS online. I see the connect, the disconnect, and the "while-connected" functions, but not the method to remain online persistently.

At best, it looks like a "jump online, execute commands, jump offline" bot.

Did I miss something?

[timvw]

I've seen also some webbased IRC scripts written in php (script puts data in db, and javascripts makes sure the page gets reloaded every 10 Seconds) and they generate a <span style='color:blue' title='I&#39;m naughty, are you naughty?'>smurf</span>

Btw, screen and irssi are my alltime favorites

[Kwah]

yo - ive made my own one but this one is more complex and has given me alot of ideas

IRC bots are indeed old news... you can learn from that as welll....

IRC bots are indeed old news... you can learn from that as welll....

Perhaps I wasnt clear enough.

I'm aware that they exist, and that they have for a considerable amount of time.


I don't understand from looking at the code what keeps them online and persistent beyond the lifetime of the script (seconds usually), and thus from timing out, and falling off of IRC.

Can someone share some insights about that?

[markl999]

The while (!feof($this->fp)){ ... } loop in the receive method keeps the script constantly looping. The
if($this->data[ping] == 'PING'){
$this->send("PONG");
}
in the parse_data method keeps the connection alive by responding to PING with a PONG, that stops the irc server 'dropping' the client.

[malcolmboston]

this is a very interesting read.........

[timvw]

everything you ever wanted to know about irc http://www.faqs.org/rfcs/rfc1459.html

[kettle_drum]

As mark said whenever the irc server sends a ping to the bot - every 180 seconds or so, the bot replies with a pong command - which just tells the server "yes im still alive". In the class constructor set_time_limit(0); means that the script wont timeout by itself due to a maximum execution time (usually 30 seconds). Hope that answers whoevers question that was.

Umm yes a script like this could be used for the wrong uses - such as to flood a server etc, but then anything can. I just say dont do it as its lame.

The other thing is that the bot sometimes disconnects unexpectely if you run if from a browser - but works A LOT better if you run it from a shell/cli.

And finally, im currently updating this bot to make it bigger and better by using modules - so that a framework bot can be made to do whatever you like by adding other modules to it e.g. chanserv, nickserv, operserv, logging, newsserv, search etc - and by adding a "fake stack" to queue commands/processes so it runs like it uses threads and so speeds it up and keeps a constant flow of data coming in through the socket connection - which also helps to ensure that it never pings out, tests so far have had it online for just over 2 days with no interruptions.

Ill keep you posted as to the arrival of the new one incase anybody wants to have a play with it.
