just remove $db parameter destructor. should this.
/*destructor*/ function __destruct(){ } if need access database destructor, can use $this->db since you've initialised in constructor.
in addition that, should remove $db parameter constructor well. it's not being used, , don't pass arguments when construct db_functions object in index.php.
