.CTP files are template files used by CakePHP, a open source development framework for PHP Web applications. .CTP files contain the PHP "view" code within the Model-View-Controller (MVC) framework. .CTP files store a template for how information is to be displayed in the PHP Web application. CTP files may contain items such as layouts (presentation code), elements (reusable segments of code), or helpers (encapsulated classes of reusable logic). .CTP files are generally stored in the CakePHP /app/views directory of a CakePHP installation.
