What steps can be taken to enhance the security of directories/files protected by HTAccess in PHP applications?

To enhance the security of directories/files protected by HTAccess in PHP applications, you can add additional layers of protection such as IP restrictions, password authentication, and SSL encryption. This can help prevent unauthorized access to sensitive files and directories.

// Example code snippet to add IP restrictions in HTAccess
<Files "sensitive-file.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.1
</Files>
