Lithium is a PHP web framework that provides tools for building scalable web applications. It has a modular architecture that allows developers to choose components like caching, security, and localization modules. Lithium uses a model-view-controller pattern and is designed to be highly configurable, extensible, and performant. It has documentation on usage, contributing to the project, and an active community for support.

Interoperability

21. 21
Any third party
code can be used
as a library.

22. 22
Libraries are managed by the
lithiumcoreLibraries class,
which handles auto-loading, service
location, and introspecting available
classes. PSR-0 compatible.

Libraries.php

Security

24. 24
Lithium provides basic functionality for user
authentication, data sanitization,
filtering input/escaping output and
CSRF protection. Form signing is in
testing.

Documentation (in code):
For example, in Libraries.php, roughly
42% of the lines of code are comments.
Not just what, but how and why.
