By the looks of it, you're looking for the singleton pattern.
final class Singleton{
private static $sql;
private static $dao;
private static $smarty;
public static function getSql(){
if(!isset(self::$sql)){
require CLASS_DIR.'Sql.php';
self::$sql = new Sql;
}
return self::$sql;
}
public static function getDao(){
if(!isset(self::$dao)){
require CLASS_DIR.'Dao.php';
self::$dao = new Dao;
}
return self::$dao;
}
public static function getSmarty(){
if(!isset(self::$smarty)){
require SMARTY_DIR.'Smarty.class.php';
self::$smarty = new Smarty;
//some config stuff
}
return self::$smarty;
}
//prevent construction/cloning
public function __construct(){
trigger_error("Singleton instantiation not allowed", E_USER_ERROR);
}
public function __clone(){
trigger_error("Singleton cloning not allowed", E_USER_ERROR);
}
}
Btw. Try to write an OO application in a manner that would not require
the require_once statement, but rather a plain require. In part,
because it's faster, but mainly because it will force you to write
your applications in a much straightforward manner. Maybe
straightforward isn't the word here, but I'm tired as hell...
