fatfreeframework.comrepositorydocs
Fat-Free Framework, also called F3, is a PHP micro-framework for building web applications. It is installed with Composer as bcosca/fatfree-core or downloaded directly, and it ships with a template engine and database support for MySQL, SQLite, MSSQL, PostgreSQL, DB2 and MongoDB. The readme says the framework’s files can be kept in a directory the web server cannot reach.
The project is maintained by F3::Factory, which publishes the core library in the fatfree-core repository. The user guide is the documentation.
Worth knowing
The readme states the GPL as the license and says alternative licensing is available for a fee.
