Hi,

I am implementing this

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::$db==null){
   dbaccess::$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.....

Try changing dbaccess to self inside the class.
