Codeigniter . htaccess remover index.php

Question

Starting working with Codeigniter and want to remove the index.php of URLS:

example.com/index.php/news/article/my_article

The problem is I have the file .htaccess in 3 different locations:

1. This in the folder application
2. This in the folder sytem
3. This in the folder public_html

Which to use to remove index.php, using this code:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

Answer 1

You should put out of any folder, ie at the root of the framework:

application/
assets/
system/
.htaccess
index.php

Then change the file application/config/config.php:

$config['index_page'] = "index.php";
$config['index_page'] = "";

Answer 2

In some cases also add:

RewriteEngine On
RewriteBase /pasta/

It happened to me, I spent hours to solve.
