Perhaps you can conjure up some sort of namespace scheme, and then use a global array to track which class files have been loaded, or which classes have been instantiated, or whatever it is you need to keep track of. In your file with a dependency: global $LOAD_STATUS; if (!$LOAD_STATUS['classes-db-queryops']) include 'lib/classes/db/queryops.php'; In lib/classes/db/queryops.php: global $LOAD_STATUS; $LOAD_STATUS['class-db-queryops'] = 1; Seems fairly cheap to do. miguel
