In a proper MVC architecture, we need to separate the view from the models that get our data, and the controllers will be responsible for handling business logic.

In our simple app, we will skip the controller layer since we just want to display the user profiles in one public facing page. The preceding function is also known as the template render part in an MVC architecture.

While there are frameworks available for PHP that use the MVC architecture out of the box, for now we can stick to what we have and make it work.

PHP frameworks can benefit a lot from the null coalesce operator. In some codes that I've worked with, we used to use the ternary operator a lot, but still had to add more checks to ensure a value was not falsy.

Furthermore, the ternary operator can get confusing, and takes some getting used to. The other alternative is to use the isSet function. However, due to the nature of the isSet function, some falsy values will be interpreted by PHP as being a set.
