Re: nested include_once()

> in lib.php > define("__LIB_PHP__",1); > in service.php: > define("__SERVICE_PHP__',1); > if (!__LIB_PHP__){ > require('lib.php'); I am not sure I was clear enough. I _want_ those include_once('lib.php') statements to be in service.php, because service.php could get included from a file other than main.php, let's say non_main.php. That file (non_main.php) does not contain a statement include_once('lib.php'), but only include_once('service_php') and so in order to use that library, service.php has to include it itself. Clear? :) So, I am trying to find out what happens in case of main.php which includes lib.php and service.php (which also includes lib.php) when I use include_once(). Does it get included TWICE? Roko
