Remove index.php from URL in CI? - codeigniter

Question

I removed index.php from the URL in CodeIgniter. I have already changed the .htaccess file data. But I want to know that is there any other way to remove the index.php from the URL or through any other .htaccess data. Means this is only a way or not.
In .htaccess file I wrote this :
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L]

Answer 1

Try This code:
RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]
and do not forget to null index value in config file
$config['index_page'] = '';

Answer 2

Try this :
Make sure you have enabled rewrite_module on your Apache modules
.htaccess
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $1 !^(index\.php|indexcp\.php?|resources|robots\.txt)
RewriteRule ^([A-Za-z0-9_/.-]+)$ index.php?/welcome/$1
Open config.php :-
$config['index_page'] = '';
$config['base_url'] = 'http://www.example.com/'; //your site name
$config['uri_protocol']= 'REQUEST_URI';
