          array("Unnao", "Trichy", "Kanpur")
      );

  private function array_flatten($array) { 
      
      if (!is_array($array)) { 
          return FALSE; 
      } 
      $result = array(); 
      foreach ($array as $key => $value) { 
          if (is_array($value)) { 
              $result = array_merge($result, $this->array_flatten($value)); 
          }
