Added another echo to PHP Playground

I am so confused. Just a second ago I couldn't return but now I can. I am
so over Windows and I'm very grateful that I have a Mac to do this with
instead. I came very close to having to do this on Windows because we're
broke... But anyway!

I understand now. I'm using VIM editor, so I have 'Insert' mode and
'Command' mode. I access 'Insert' mode by pressing 'i' and I can access
'Command' mode by pressing 'Esc'

I love technology but if it weren't for the Internet I'd have no idea as
to what I'm doing. You'd think the documentation would help me out, but
it's usually so verbose -- Documentation for things like this. Reading the
Git documentation alone is very difficult.

This was a test to see if I can add a description to my GitHub commits by
entering ViM and adding more paragraphs of text. Hopefully all of this
text will be in the commit description and the first line of what I'm
seeing in this editor will be the commit message.
