Includes and paths confusion

Hello all, Im having some problems understanding why some requires() are failing. Let me see if i can describe what's going on clearly... I have this: nick@communicontent > ls ads/ config.inc db.inc funcs.inc init.inc where ads/ is a whole huge set of scripts from an existing setup. ads/ was originally placed on its own domain as it's a version of phpadsnew and runs as a server all by itself. I moved ads/ to this directory to try to troubleshoot and make things clearer. db.inc has these lines: require_once("ads/admin/config.php"); require_once("lib-statistics.inc.php"); require_once("lib-zones.inc.php"); require_once("config.inc.php"); require_once("lib-db.inc.php"); require_once("lib-dbconfig.inc.php"); warning: main(../config.inc.php): failed to open stream: No such file or directory in /var/www/localhost/vhosts/payment.communicontent.com/modules/partners/inc/ads/admin/config.php on line 33. Fatal error: main(): Failed opening required '../config.inc.php' (include_path='.:/usr/lib/php') in /var/www/localhost/vhosts/payment.communicontent.com/modules/partners/inc/ads/admin/config.php on line 33 So, why does this not happen when ads/ is on its own domain? I can see it has something to do with relative paths, but even when i try to work with chdir() i still get no joy. I just can't figure out what the issue may be, so any pointers in the right direction would be hugely appreciated. thankyou! -- Nick Wilson Tel: +45 3311 2250
