Roflbot/Alarm/Remote

Recommended Posts

I've been watching Hak.5 for a while I love Darren's php/apache segments. When I saw the roflbot I knew I had to do something with it so I decided to make the roflbot more tamagochi-like.

I've bascially taken the roflbot code and but added another webpage to control it from, where you can feed, play and make it sleep. I've also used imagemagick and ffmpeg to create different videos for each of the actions depending on the time of day and the temperature.

And comments will be greatly appreciated as I'm looking to actually add in the alarm part of this project so that the roflbot actually does something the same way the rss alarm clock did, but thought I would just get this out and see what people though. I've also attached the pictures that I used if you would like to try it out. My artistic skills may not be as good as Darren's, but at least I tried to use arrays :P.

roflbot.php

<?php
$loopcount=1;
$currbg =  array('blink'=>'','dance'=>'','eating'=>'','fight'=>'','hungry'=>'','sleep'=>'',
	'angry'=>'','tired'=>'','walk'=>'');

$prevbot = '';
$roflbotarray = array('angry','blink','dance','eating','fight','hungry','sleep','tired','walk');
$roflbotrand = array('blink','fight','walk');
$roflbot = $roflbotrand[0];
$hunger = 0;
$energy = 100;
$fun = 100;
$videochoice = array ('angry'=>5,'blink'=>6,'dance'=>7,'eating'=>8,'fight'=>9,'hungry'=>10,
	'sleep'=>11,'tired'=>12,'walk'=>13);

Code is vulnerable to PHP code injection which would leave your site owned, not to mention your entire box in all probability. You should really make sure to filter all of your inputs.

Something like this in control.php?

if (isset($_GET['action'])) {
    $action=$_GET['action'];
    if ( $action == 3 || $action == 7 || $action == 2 ){
        $file=fopen("action.txt","w");
        fwrite($file,$action);
        fclose($file);
    }
}
