Description
ConfigPress is a development tool with the main intent to avoid any hard-coding and give an easy and flexible interface to manage all your website custom settings (options).
With ConfigPress you can define your own custom option or group of options and retrieve them in your code by simply calling ConfigPress::get(‘option_name’) method. This way you do not have to hard-code any sensitive or environment specific options in your custom code.
