html - Why Have index.php in URI in CodeIgniter Call -

-

codeigniter gives example blog.php

<?php class blog extends ci_controller {          public function index()         {                 echo 'hello world!';         } }

and calls by

example.com/index.php/blog/

question why have index.php in uri?

you want know why there index.php in url? there simple answer, request under codeigniter given index.php resolves controller. 1 usally use mod_rewrite masks index.php. php interpreter not have concept of controller, maps uri file , gives post , parameters. need file which translates uri in controller call.
