Consider using the __autoload() function in php. (also the SPL autoloading features). It's a way to tell php to load a file when it cannot find a definition for a CLASS (only for classes). I don't know how you have set-uped your project, but in mine the only place in the project where I use include is thie __autoload() function. In other words - php supports load-on-demand for classes.
