If you're using PHP4 stop now and turn off overloading: define('DB_DATAOBJECT_NO_OVERLOAD', 1); overloading in PHP4 is broken (it breaks implicit pass-by-reference in method calls). And no, it's not calling itself. Note the extra underscore (_). __call is the method PHP calls. _call is an internal method on the DB_DO class which does the real work. -- Justin Patrin
