Separation of Concerns

Separate the data the view using templates!

• PHP code connects to database and does query and gets the data
• Define how to display that data with a template (generic term, not referring to <template> element) -- and in this case, we'll use Mustache templates! Handlebars syntax is compatible with Mustache!
  Note that Twig is a popular template system to use with PHP.
  And note that there are many other template systems, including Liquid.
