Base url for Image / script / css path. site url for Address url for accessing the controllers

echo base_url(); // http://example.com/path/to/your/ci/install
echo site_url(); // http://example.com/path/to/your/ci/install/index.php

What if I remove index.php with .htaccess? Can I use base_url all times? – Lucas Bustamante Mar 04 '17 at 17:06
@KumarV, I just want to know what is the best for anchor tag? – user9437856 Jun 10 '18 at 17:53
@user9437856, if you want to use CI anchor , then have to use `anchor(uri segments, text, attributes)`. Otherwise you can use plain html `a` tag with `site_url()` in href. – Kumar V Jun 11 '18 at 04:30

To clear all your doubts you have to read CodeIgniter Manual.Please Click Here

base URL

Returns your site base URL, as specified in your config file. Example: echo base_url();

This function returns the same thing as site_url, without the index_page or url_suffix being appended.

Also like site_url, you can supply segments as a string or an array. Here is a string example: echo base_url("blog/post/123");

site URL

Returns your site URL, as specified in your config file. The index.php file (or whatever you have set as your site index_page in your config file) will be added to the URL, as will any URI segments you pass to the function, and the url_suffix as set in your config file.

You are encouraged to use this function any time you need to generate a local URL so that your pages become more portable in the event your URL changes.

Segments can be optionally passed to the function as a string or an array. Here is a string example: echo site_url("news/local/123");

The above example would return something like: http://example.com/index.php/news/local/123

Here is an example of segments passed as an array: $segments = array('news', 'local', '123');

echo site_url($segments);

No doubts the answers by kumar_v and nidheesh are absolutely correct . However , I would like to add when to use base_url() and the site_url() . Basically one can use site_url() while creating links for controllers whereas base_url() can be used where we need to create urls for the assets like loading a css or js file or some image .

What I always prefer is to use site_url() for creating links to controllers or ajax urls and base_url() for loading assets .
