Chat bot code help

[2_tailed_tech]

I a php based chat bot used for deviant art chat and there is a vend module that simulates and in chat. The commands typed in chat cause the bot to add despense and remove items form a master vending list. I cannot seem get the delete command to work. In chat the command will take and the bot will say the item has been removed however the removed item stays on the list and can be requested again.

 

The codes as follows

<?php

 

// Add drinks using same syntax

global $config;

if(empty($config['vending_machine'])){

$config['vending_machine']=array(

  'coke',

  'diet coke',

  'pepsi',

  'diet pepsi',

  'lemonade',

  'wine',

  'beer',

  'mountain dew',

  'tea',

  'electictocnet doll',

  'sprite',

  'coffee',

  'root beer',

  'hot chocolate',

  'cream soda',

  'fuzzy dice',

);

sort($config['vending_machine']);

}

// Quality of vending machine

// High # = Better quality

// 0 quality always jams

$quality=5;

 

$found=in_array(strtolower($argsE[2]),$config['vending_machine']);

switch(strtolower($args[1])){

case '':

$dAmn->say("$from: Please order something.", $c);

break;

case 'add':

if($found){

$dAmn->say("Can't add, the machine already stocks {$argsE[2]}.", $c);

}else{

$dAmn->say("{$argsE[2]} added!",$c);

$config['vending_machine'][]=strtolower($argsE[2]);

sort($config['vending_machine']);

}

break;

case 'del':

if($found){

$dAmn->say("{$argsE[2]} removed!",$c);

unset($config['vending_machine'][strtolower($argsE[2])]);

}else{

$dAmn->say("Can't remove, the machine doesn't stock {$argsE[2]}.", $c);

}

break;

case 'list':

$dAmn->say("The machine stocks: ".implode(", ",$config['vending_machine']),$c);

break;

default:

if(!in_array(strtolower($argsF),$config['vending_machine'])){

$dAmn->say("$from: The machine doesn't stock {$argsF}.", $c);

return;

}

$items=count($config['vending_machine']);

$max=intval(floor(($items*$quality)+1));

$get=mt_rand(1, $max);

$jam=intval(floor(.5*$items));

$oops=$items;

$i=array_rand($config['vending_machine']);

$vend=$config['vending_machine'][$i];

if($vend==strtolower($argsF)) $get=$oops+1;

if($jam>$get) $dAmn->say("$f It's jammed. :thumb14796735:", $c);

elseif($oops>$get) $dAmn->say("$f You got a {$vend}. :shakefist: ", $c);

else $dAmn->say("$f Here is your {$argsF}.", $c);

break;

}

?>
