but forgot to add PHP support, and there are a whole bunch of situations that can lead to source code exposure. You can prevent source code from being exposed by saving as much PHP code as possible outside of your website's home directory. At the very least, it's a good idea to keep all of the included files outside the home directory. Some methods can limit the
