There is a class in php that can handle excel functions  http://www.phpclasses.org/package/892-PHP-Financial-functions-with-the-Excel-function-names-.html

You will have to implement this in order to cater to your needs.

I am assuming you know basic PHP scripting here.

Basically you need to download the code from the link i provided and then include in the script where you would like to do the calculation.

Here is a sample code picked from there.
<?php
/**
