In this chapter we have reviewed and practiced CI naming conventions, rules, and usage with a set of examples for parameters, classes, controllers, models, helpers, libraries, and views.

Following the naming conventions we have reviewed CI configurations. We reviewed the major configuration files, such as config.php, database.php, autoload.php, and routes.php in depth. We also reviewed how we can use the configuration parameters while configuring several databases to be used in our project. In addition to it we also saw how we can add more project-specific configurations.
