添加site / index.php / city作为codeigniter url路由无法正常工作

I have writing codeigniter URL routes for my site, the route is

$route['index.php/([a-zA-Z0-9---_%])+'] = 'site/index/$1';

when i try to access the link like as below

http://localhost/site/index.php/india

is not working, it redirects to 404 page.

If you have a link

http://localhost/site/index.php/india

You need write this route:

$route['site/index.php/(:any)'] = 'site/index/$1';
