Hi, I am implementing this

try comparing this rewrite with your version: abstract class dbaccess { static $db = null; private static function init() {

    if (dbaccess::$db))

return;

    dbaccess::$db = new mysqli("localhost",USER,PASSWD,DB);
    if(mysqli_connect_errno()) 	

throw new Exception('cannot connect to DB'); } public static function getDB() { self::init(); return dbaccess::$db; } } try { $db = dbaccess::getDB(); $db->query("SELECT foo FROM bar WHERE qux=1"); } catch (Exception) { die($e->getMessage()); }

class dbaccess{ static $db=null; static $othervar=33;

      private  function dbaccess(){
    dbaccess::$db= new mysqli("localhost",USER,PASSWD,DB);
    if(mysqli_connect_errno()){
      echo "no way";
    }

}

    public static function GetDb(){

if(dbaccess::$db==null){

dbaccess is a static class, you should not be constructing it here it!

dbaccess::$db= new dbaccess(); } return dbaccess::$db;

      }

} $db=dbaccess::GetDE(); $db->query(..................); will fail...with Call to undefined method dbaccess::query() apparently $db is of type dbaccess... and thus has not does not have query implemented.... any hhelp appreciated..... JCG
