如何在codeigniter中的base_url（）中添加index.php

Question

In general when we use site_url() in anchor tag in php code it auto insert "index.php" before the controller like

/index.php/controllerName/methodName

But in base_url it doesn't insert "index.php". I want to add auto index.php before the controller how site_url() works.

Already I searched and understood that the change will be in config file. But want to know the specific answer what I need to change.

Base URL should be absolute, including the protocol:

$config['base_url'] = "http://somesite.com/somedir/";

If using the URL helper, then base_url() will output the above string.

Passing arguments to base_url() or site_url() will result in the following

$config['index_page'] = "index.php";:

echo base_url('assets/stylesheet.css'); // http://somesite.com/somedir/assets/stylesheet.css
echo site_url('mycontroller/mymethod'); // http://somesite.com/somedir/index.php/mycontroller/mymethod
