Introduction

This just uses googles own calculator..

heres what the output looks like

[12:49][RandomUser] !calc 23*4/56^2/456+8999
[12:49][PHP_Bot] (((23 * 4) / (56^2)) / 456) + 8999 = 8999.00006

full instructions here:
http://www.google.co.uk/intl/en/help/calculator.html

Grab the Code

<?php
 
// Google calculator
function do_calculator($query){
	if (!empty($query)){
		$url = "http://www.google.co.uk/search?q=".urlencode($query);
		$f = array("Â", "<font size=-2> </font>", " &#215; 10", "<sup>", "</sup>");$t = array("", "", "e", "^", "");
		preg_match('/<h2 class=r style="font-size:138%"><b>(.*?)<\/b><\/h2>/', file_get_contents($url), $matches);
		if (!$matches['1']){
			return 'Your input could not be processed..';
		} else {
			return str_replace($f, $t, $matches['1']);
		}
	} else {
		return 'You must supply a query.';

I like how you've expanded on an existing snippet, but this may be a bit advanced for some users. You've got a handful of include statements for files nobody has access to, so that might confuse some folks. Overall this is a helpful addition.

nice....

I'd use switch to, if I did do it again....

but what I've done is just had includes for all the files/commands

=)
