syntax

For documenting on Drupal web sites steps taken on the command line, Agaric would like syntax highlighting of the sort GitHub is using. Note that it is adding a class to the pre tag, and then using spans within that!

Perhaps could be added as a feature to the Code filter module.

Once it's set up right, you can use :make % to check your PHP syntax before loading the code in a browser.

Solution

(From rnreekez in the comments, syntax modified to conform to Drupal's more verbose coding standards.)

Technically you want your switch statement to process for all things TRUE.
