It's a nice system in PHP. There are quite a few of them. Like ledger-cli [1] in C++ and emacs lisp, hledger [2] in Haskell and beancount [3] with fava [4] in python.

We used ledger-cli and beancount with fava and built automatic creation of accounting entries using machine learning and Bayesian alogrithms by analyzing bank and credit card statements. You can use powerful icsv2ledger [5], smart importer [6] and the awesome list [7] to get importers for various banks and other utilities.

Note: corrected the entry for ledger-cli, its primarily written in C++ with some emacs lisp scripts.
