or try htaccess
RewriteEngine On
RewriteRule ^([^/]*)$ /user_controller/newfunction/$1 [L]

Answer 2

/application/config/routes.php
$route['/all/other/routes/must/come/first!'] = "wherever/you/want";
$route['/(:any)'] = "/user_controller/newfunction/$1";

Answer 3

Its easier to use CI routing system found at application/config/routes.php
$route['(:any)'] = 'user_controller/newfunction/$1';
Don't forget to set your base url at application/config/config.php
$config['base_url'] = 'http://www.domain.com/';
Add remember to remove the index.php in the url. Edit your .htaccess file at the root of your site
RewriteEngine on
RewriteCond $1 !^(index\.php|assets|_searches|robots\.txt|favicon\.ico)
RewriteRule ^(.*)$ /index.php/$1 [L]
now in your user_controller, the function newfunction will look like this:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class user_controller extends CI_Controller {
public function __construct() {
parent::__construct();
// load things like models, libraries, helpers
}
function newFunction($slug)
{
echo 'hello my name is'.$slug;
}
}
when you visit http://www.domain.com/nash, your code should print out nash
