Need advice on SEO friendly URLs

I have problems with routing and mod_rewrite so I would go for this simple(?) solution

Because there are only five continents then have a controller for each continent.

1. NOT REQUIRED: // Each controller inherits a common MY_Controller
2. the index function is passed two variables, $country and $city.
3. these two parameters are used to query a database table
4. the results are passed to a common view function.

Code:

<?php

class Asia extends Controller /* MY_Common_Controller NOT REQUIRED */
{
//==============================================================    
//
// The Asia controller
//   usage:
//       http://mytravelsite.com/Asia/Thailand/Bangkok
//
//==============================================================    
function index($country='', $city='')
{
   $view_file = 'the_home_page';  // default to no parameters
   if ('' != $country) // Yes we have a country
   {
      $data      = $this->my_model->Please_can_I_have_details_for('Asia', $country, $city);
      $view_file = 'this_holiday';  
    }
    $this->show_me_the_view_for($view_file, $data);

}//endfunc

}//endclass

 
 
 
edit: removed MY_Common_Controller, added Home page is no parameters passed.
N.B. Please note this code has not been tried and tested.
