Fabulous PHP frameworks: Qcodo, Lithium, Seagull, and Yii
Alternative PHP frameworks offer such advantages as code generation, prebuilt modules, and application performance
Lithium supports the MongoDB database server. MongoDB describes itself as a cross between an RDBMS and a key/value pair storage system, and it has the unique feature that you don't have to create a table before storing data into the database. (MongoDB's analog to a table is a collection.) MongoDB will create the persistent storage system the first time you access it. Lithium also supports "standard" relational databases like MySQL, PostgreSQL, and SQLite, as well as SQL Server through an official plug-in.
Lithium appears to be still under construction (at the time of this writing, it was at version 0.9.9), and its roughness shows in the documentation. For example, the documentation under the console command reads: "More documentation will be placed here as the built-in commands become more usable and finalized." Nevertheless, there is much promise here, and we hope Lithium progresses at full speed.
