If PHP, then ProcessWire [1]. ProcessWire is a Content Management System, not a CMS which includes a design or layout system like Wordpress. So as a developer you are free to develop the front-end the way you like. Which is easy with the provided API. I use it for API's, small and huge websites. Love it.
