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.

Look at this:
