CodeIgniter URLs

• Standard “query string” approach
• Dynamic systems
• Segment-based approach

URI Segments

It is following MVC Approach

jayakumar.xyz/class/function/ID

1. The first segment represents the controller class 
2. The second segment represents the function (method) class
3. The third segment represents the ids, variable or passing any variables class 

The URI Library and the URL Helper contain functions that make it easy to work with your URI data. In addition, your URLs can be remapped using the URI Routing feature for more flexibility

Removing the index.php file

By default, the index.php file will be included in your URLs:

jayakumar.xyz/index.php/codeigniter/docs/urls

If your Apache server has mod_rewrite enabled, you can easily remove this file by using a .htaccess file with some simple rules.

Example: .htaccess file

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

After using .htaccess file default url changed

jayakumar.xyz/codeigniter/docs/urls

Enabling Query Strings

In some cases you might prefer to use query strings URLs:

jayakumar.xyz/index.php?c=products&m=view&id=345

CodeIgniter optionally supports this capability, which can be enabled in your application/config.php file.

$config['enable_query_strings'] = FALSE;
$config['controller_trigger'] = 'c';
$config['function_trigger'] = 'm';
