Open Source Finance Modules in PHP

I am searching for Open Source Finance scripts such as Account Payable, Account Receivable,开发者_运维技巧 General Ledger etc in PHP. But I couldn't find a good one.

Is there any such open source scripts in PHP available over the web for download?

If so, could you please give me the links.

Thanks

Would a list of open source accounting software help? The "Further details" section shows there is a few written in PHP.
