There is a financial function in Excel known as XIRR. I need to calculate it in PHP. Is there any class available for this? It seems like a very complicated thing to do. 🙁
This looks promising, but I've not used it so cannot vouch for it: http://www.phpclasses.org/package/892-PHP-Financial-functions-with-the-Excel-function-names-.html
Great, thanks. 🙂
