Can relative paths in .htaccess files be used effectively for file access control in PHP?

Relative paths in .htaccess files can be used effectively for file access control in PHP by restricting access to certain directories or files. This can help enhance the security of your PHP application by preventing unauthorized access to sensitive files or directories.

# .htaccess file in the directory you want to protect
<Files "sensitive-file.php">
    Order allow,deny
    Deny from all
</Files>
