	function dump_query_number() {

	}
}

$queries i $sqldump su globalno vidljive. nesto poput

function dump_sql() {
		return $this->$sqldump;
	}

Nece da radi (dobijam cannot reference empty resource ili sl). Kako $queries i $sqldump da budu vidljive samo unutar klase mysql_link. Primer mogu i echo $link_id->dump_query_number(); i echo $queries;
