How do I prevent someone from viewing a directory?

[narutodude000]

If someone goes to a directory in my website without a index.php on a browser, he can view all of the files in that directory.
Are there ways to prevent this? (other than adding a index.php)

The easiest way to do this is to edit the .htaccess in the root directory of your website. Add

Options -Indexes

to the file. This will disable directory listing in every directory of your website.

This returns a 404 page right? Thanks.

Turning off directory listing will cause a 403 unauthorized to be returned.
