li₃

li₃ is the first and only major PHP framework built from the ground up for PHP 5.3+, and the first to break ground into major new technologies, including bridging the gap between relational and non-relational databases through a single, unified API. li₃ is the first framework to give you the best of both worlds, without compromising either.

In fact, the framework's API is intentionally designed to allow you to "grow out of" the framework and into your own custom code over the course of your application's lifecycle, if your needs require. li₃ takes full advantage of the latest PHP language features, including namespaces, late static binding and closures.

li₃'s innovative method filter system makes extensive use of closures and anonymous functions to allow application developers to "wrap" framework method calls, intercepting parameters before, and return values after.

The framework integrates the latest storage technologies, including MongoDB, CouchDB and Redis, with plugin support for Cassandra, ElasticSearch and others. li₃ gives you full control over your application, from filters to dynamically modify framework internals, to dynamic dependencies to extend and replace core classes with application or plugin classes, to heavy use of adapter-oriented configurations, to make it seamless to move between different technologies and options.
