I am. This is not an answer, but it is a solution. I don't ever rely on include_once. If someone else uses my include files they may not use include_once. Instead I use the old C/C++ trick of defines: <?php if (!defined('SOME_INCLUDE')) { define('SOME_INCLUDE', TRUE); // Place code here } ?> I use the following structure for creating unique constants to prevent collisions: {projectname}_{classname}( include ? _INC:) A global class outside my projects: _CLASS_NAME The class FooBar in my Rule The World project: RULE_THE_WORLD_FOO_BAR The config include in my Rule The World project: RULE_THE_WORLD_CONFIG_INC -- Adam Bregenzer adam@bregenzer.net http://adam.bregenzer.net/
