Hi Tinker,

Yes PHP is not hard, *for someone who has programmed before*. It can be very difficult and challenging, but it is a very good language to be your first language. It is incredibly forgiving compared to alot of other languages, and thus will help you understand things more.

root directory ~ This is the top level directory from which all other directories stem. In windows, C:\ could be considered a root directory.

Local host ~ This references the current server you are on. If you have a database on your current server, you would access it by referencing 'localhost'
