Question

I was wondering how one could make codeigniter style url segments on a project.

Aside from an htaccess rule to capture the segments, how can this be done in PHP?

After snooping around the codeigniter source code, i could not find any reference to an htaccess file that captures the usage.

Any idea on how this can be done?

Assuming you are passing ALL requests to index.php via Apache mod_rewrite or Nginx:

// Get the current URL path (only) and convert encoded characters back to unicode
$path = rawurldecode(trim(parse_url(getenv('REQUEST_URI'), PHP_URL_PATH), '/')));

// array merge with defaults
$segments = explode('/', $path) + array('home', 'index');

//First two segments are controller/method
$controller = array_shift($segments);
$method = array_shift($segments);

// @todo serious security checking here!

// Finally, load and call
$controller = new $controller;
$controller->$method($segments);

Your controller would look like this

class Home
{
    public function index($params)
    {
        print_r($params);
    }
}
