php - How to call my mysqli_result class -

i create mysqli_result class :

class mysqli_result{     private $res;     private $row;     private $field=0;  private function __construct(){  }  static public function get($res,$row,$field){     $res->data_seek($row);      $datarow = $res->fetch_array();      return $datarow[$field];  } 

}

the main problem got 3 parameters while in of old mysql_result got 2 parameters ($res,$field).

so don't know suppose put in $row parameter.
