Hi internals

Regarding the matter of a sandbox, one of my colleagues open sourced a =
Laravel sandbox that runs straight in the browser and uses docker =
containers, with a little work you can extract away the Laravel part and =
have it run plain PHP. Here's the source: =
https://github.com/spatie/tinker.app =
<https://github.com/spatie/tinker.app> and here's it running: =
https://tinker.app/ <https://tinker.app/>

On topic now, regarding the promo page: this kind of marketing is where =
PHP lacks a little bit, so I think it's a great initiative. A simple one =
pager just to promote PHP, one you can share with both PHP and non-PHP =
developers, and teases the right amount to get some people interested. A =
perfect page to share on hackernews, reddit, twitter and the likes. I =
think it's a great first step!

Kind regards
Brent
