What are the best practices for protecting PHP files and sensitive data from being accessed through download managers?

To protect PHP files and sensitive data from being accessed through download managers, you can use a combination of server-side security measures such as file permissions, htaccess rules, and encryption for sensitive data. Additionally, you can implement user authentication and access control to restrict unauthorized access to your PHP files.

// Example of restricting access to sensitive PHP files using htaccess rules
<FilesMatch "\.php$">
    Order allow,deny
    Deny from all
</FilesMatch>
