How can PHP code be protected from being edited or viewed in an editor while still being accessible via Apache?

To protect PHP code from being edited or viewed in an editor while still being accessible via Apache, you can use the `php_flag engine off` directive in your .htaccess file. This directive disables the PHP engine for the specified directory, preventing the code from being executed or displayed. ```apache <Files "*.php"> php_flag engine off </Files> ```
