Need help with auto_prepend_file

Our website relies heavily on include files. We have a single include file that is 'auto prepended' to every php file on the site using the auto_prepend_file directive in php.ini. This include file does an include_once on other include files. Also, most parts of our code include other page components such as our menu bar from other .inc files. Should we be using auto_prepend_file? It seems like this does not do an include_once and when we turn error_reporting = E_ALL we are seeing a lot of errors on variables that have already been defined and such.
