How to set Favicon in Codeigniter
It depends on your organization. I usually put the favicon.gif file in the web root folder, so the URL would be yourdomain.com/favicon.gif
Then you have to add the following line of code into your HTML <head>:
<link rel="icon" href="<?=base_url()?>/favicon.gif" type="image/gif">Assuming that the URL Helper is loaded in CodeIgniter. You can load it via $this->load->helper('url'); or add it into the autoload helper array in your config folder.
You could load the HTML helper and use <?php echo link_tag('favicon.ico', 'shortcut icon', 'image/ico'); ?> on the <head> html tag.More information in http://codeigniter.com/user_guide/helpers/html_helper.html#link_tag
I have used this in my code and its working fine
<pre><link rel="icon" href="<?php echo base_url(); ?>favicon.ico" type="image/gif"></pre>
