remove index.php with alternative routing in codeigniter -

i'm working on project in codeigniter doesn't use standard routing.php file. calls functions this: test.vi/index.php/controller/function.

my goal remove index.php url htaccess rewrite:

 rewriteengine on  rewritecond %{request_filename} !-f  rewritecond %{request_filename} !-d  rewriterule .* index.php/$0 [pt,l]  

and config.php change:

$config['index_page'] = ''; 

my question need route controllers/functions in route.php or can done without using route.php file?

first make sure enabled mod_rewrite in httpd.conf:

to add/make sure exsits line

loadmodule rewrite_module modules/mod_rewrite.so 

then create .htaccess in codeigniter root folder (next index.php file) not application folder.

.htaccess

directoryindex index.php rewriteengine on rewritecond $1 !^(index\.php|img|css|js|robots\.txt|favicon\.ico) rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d rewriterule ^(.*)$ ./index.php/$1 [l,qsa] 

codeigniter take care of routings you; for

controlers/welcome.php method=hello u can access

http://localhost/welcome/hello

its not laravel need add route; codeigniter automatically fitch controller you. unless have stored in different location or inside subfolder dont need touch route.php except setting default route.
