As noted in Laravel's documentation, setting debug to true on a production application is a significant security risk that should never happen. Most frameworks allow you to detect the environment automatically or set it via a server variable.
The best practice is to store the config file one directory the web root ( /home/username/private_html/config.php ). This makes it impossible for a browser to access directly because the directory is not served by the web server. Most modern applications, including Cloudways' infrastructure, utilize a private_html folder for this purpose, enhancing security significantly. Moving the configuration file to a non-public folder adds a critical layer of security for your website.
