Remove index.php from URL in code Igniter - php

Question

i have read posts regarding this but that did not gave answer to my problem
i have set everything i found on forums of code igniter and SO's questions
currently i have following settings :
.htaccess file
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
#'system' can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
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
#This last condition enables access to the images and css folders, and the robots.txt file
RewriteCond $1 !^(index\.php|(.*)\.swf|images|robots\.txt|css|docs|cache)
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>
<IfModule !mod_rewrite.c>
# If we don't have mod_rewrite installed, all 404's
# can be sent to index.php, and everything works as normal.
ErrorDocument 404 /application/errors/404.php
</IfModule>
and i also have set $config['index_page'] = '';
but this is not working there is not change in URL
if i type *http://localhost:8088/crud_demo/index.php/login* it works but if i type *http://localhost:8088/crud_demo/login* it shows Not Found Error
My Route config
$route['register'] = "register";
$route['manage'] = "manage";
$route['default_controller'] = "login";
$route['404_override'] = '';

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.

RewriteRule ^crud_demo/(.*)$ crud_demo/index.php/$1

I think CodeIgniter has it's own way of routing URLs like other PHP frameworks. Take a look here: http://codeigniter.com/user_guide/general/routing.html

If crud_demo is a subfolder of your root dir then you should change
RewriteBase /
to
RewriteBase /crud_demo
