phpMoneyBooks is a PHP/MySQL program that aims to be a Web-based QuickBooks replacement. It can manage bank accounts and check registries; manage customers and create statement charges; print statements to bill customers; and display profit and loss reports. The design is modular so that features can be added by any PHP/MySQL developer. With new modules, you can direct the user to a URL. Clients can log in and check their own bills and pay online, create memorized billing cycles with Auto Billing (good for recurring billing), and more.
phpdocr will download, prettify, and output PHP documentation for the function or class that is supplied on the command-line, much like perldoc does for Perl and ri does for Ruby. Unless you explicitly tell it not to, phpdocr will also cache the documentation locally for fast retrieval in the future.

phpivr is an Asterisk AGI application which uses PHPAGI to organize Interactive Voice Responses. It doesn't need extensions.conf changes and dialplan reloading if you want to modify the IVR menu, it reads phpivr.conf on the fly. It supports unlimited levels of IVR menus. It is a standalone tool (you do not need to install FreePBX with all its functionality), does not require additional exotic libraries, and is easy to integrate into your own application.
