What are some common methods to protect PHP code from unauthorized downloads?

Unauthorized downloads of PHP code can be prevented by using methods such as disabling directory browsing, setting proper file permissions, and using .htaccess rules to restrict access to sensitive files. By implementing these measures, you can protect your PHP code from being accessed or downloaded by unauthorized users.

// Disable directory browsing
Options -Indexes

// Set proper file permissions
chmod("yourfile.php", 0600);

// Restrict access to sensitive files using .htaccess
<Files "sensitivefile.php">
    Order Allow,Deny
    Deny from all
</Files>
