laravel in subdirectory but route points to parent directory - laravel

Question

i have a problem in laravel route i don't know how to fix it!
well first of all i should say my webserver is lighttpd and there's no way to change it to nginx or apache if you want to say use another webserver... :D
well, my project was in "/path/to/some-where/htdocs" and my domain was "example.com"
and in "lighttpd.conf" i pointed "example.com" to "/path/to/some-where/htdocs/public/" and everything worked well and laravel worked fine, but because of some reasons i made some changes cause we needed "example.com" domain for some other projects
i moved project to "foo" subdirectory so now my project path is "/path/to/some-where/htdocs/foo/" and also i made some changes in lighttpd and pointed "example.com/foo" to "/path/to/some-where/htdocs/foo/public/"
also i changed APP_URI in .env to "http://example.com/foo"
but when i open "example.com/foo" it shows me "route not found" error, laravel it's working but it doesn't recognize "/foo" as base directory and when i put all of routes in a route group with "foo" prefix it works fine!
for testing i made these routes
Route::get("/", function(}{return "sweet home!";));
Route::get("/{slug}", function($slug}{return $slug;));
when i open "example.com/foo" it should show me "sweet home" but instead, it shows me "foo" cause as i said laravel doesn't recognize "foo" as base directory
it seems i should change base directory or base uri of project but i couldn't find anything
as i said i changed APP_URI, and also i put
RewriteBase /foo/
in .htacess but no result!

Answer 1

You should prefix your routes this way :
Route::group(['prefix' => 'foo'], function() {
Route::get("/", function(}{return "sweet home!";));
Route::get("/{slug}", function($slug}{return $slug;));
});
