CodeIgniter
PHP MVC web framework with a small footprint and few configuration requirements.
codeigniter.com/repositorydocs
CodeIgniter is a PHP MVC framework for building web applications. New projects start from the appstarter template. The deployment guide recommends setting the document root to the application’s public folder, which keeps the rest of the code out of the web root. Templates are plain PHP files or use the framework’s view parser. The CodeIgniter Foundation has managed the project since 2019, after the framework was developed at EllisLab and later acquired by the British Columbia Institute of Technology. An experimental worker mode on FrankenPHP is documented.
