Quite easy to understand:
look at the code generated by your web server after php code has been
interpreted (view source in your IExplorer menu).
When you use /n, the code continues on a new line.
If you don't use /n, the code continues on the same line.
In your example /n is used to facilitate the reading of the HTML code
generated by the web server.
If you use SQL database, /n will be usefull to introduce "new lines" in a
single text stored in only one field of your database...
