I want to remove index.php from codeigniter url

Change AllowOverride None to AllowOverride All in my virtual host file at /etc/apache2/sites-available/000-default.conf in ubuntu Change AllowOverride None to AllowOverride All in my virtual host file at /etc/apache2/sites-available/default.conf in windows

<VirtualHost *:80>
    ServerAdmin webmaster@localhost

    DocumentRoot /var/www
    <Directory />
            Options FollowSymLinks
            AllowOverride All    <---- replace None with All
    </Directory>
    <Directory /var/www >
            Options Indexes FollowSymLinks MultiViews
            AllowOverride All   <---  replace None with All
            Order allow,deny
            allow from all
    </Directory>
....

Then put this code in .htaccess file in root folder in codeigniter

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

It will definately work.

From http://ellislab.com/codeigniter%20/user-guide/general/urls.html - Try

RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]

after all said by friends, you have to do another thing (I think you are doing it on localhost):

First, double check the suggestions: then go to windows tray, right click on WAMP icon, and then click on it , go to Apache menu, and then to modules and then check for rewrite_module to see if it is checked or not, and click on it if you find it unchecked (means disabled) to enable it. Now try again and report it...

You just have to create .htaccess file on the root application folder or edit it if you already have. The following .htaccess file works for me.

.htaccess

# BEGIN ci
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

RewriteCond ${REQUEST_URI} ^.+$
RewriteCond %{REQUEST_FILENAME} \.(gif|jpe?g|png|js|css|swf|php|ico|txt|pdf|xml)$
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /Codeigniter

#Removes access to the system folder by users.
#Additionally this will allow you to create a System.php controller,
#previously this would not have been possible.
#'system' can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php?/$1 [L]

#When your application folder isn't in the system folder
#This snippet prevents user access to the application folder
#Submitted by: Fabdrol
#Rename 'application' to your applications folder name.
RewriteCond %{REQUEST_URI} ^application.*
RewriteRule ^(.*)$ /index.php?/$1 [L]

#Checks to see if the user is attempting to access a valid file,
#such as an image or css document, if this isn't true it sends the
#request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>

so not olx as it's a controller and not a folder

in config

$config['base_url'] = '';
$config['index_page'] = '';

in route

$route['default_controller'] = "olx";

and move your D:\xampp\htdocs\Codeigniter\application\controllers\olx\olx.php to D:\xampp\htdocs\Codeigniter\application\controllers\olx.php

and olx should look like

class olx extends CI_Controller {


 public function __construct()
   {
       parent::__construct();

 }


public function index()
{

    echo "test";
    // or $this->load->view('olx/overview.php', $data);

}

}

and try localhost/codeigniter/ or localhost/codeigniter/olx
