If you work with CodeIgniter, you will soon learn fast enough that the CodeIgniter framework, by default, uses the index.php in its URL. Here’s an example of how the URL would look like with the index.php being visible.
Table of Contents
CodeIgniter URL
http://example.com/index.php/news/article/my_article
.htaccess
To remove the index.php from the URL, you will need to add mod rewrite rules to the .htaccess file in your main CodeIgniter directory. Use this code. Change the rewrite base to your own settings.
RewriteEngine On
RewriteBase /ci/
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php?/$1 [L]
RewriteCond %{REQUEST_URI} ^application.*
RewriteRule ^(.*)$ /index.php?/$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
ErrorDocument 404 /index.php
config.php
In addition, you will need to edit the /application/config/config.php file. Make sure to remove index.php reference within the file.
$config['index_page'] = '';
