Using enums instead of class constants

I’ve been enums lately instead of relying on class constants. The myclabs/php-enum package provides a nice implementation. The readme lists the benefits of doing so:

Using an enum instead of class constants provides the following advantages:

  • You can type-hint: function setAction(Action $action) {
  • You can enrich the enum with methods (e.g. format, parse, …)
  • You can extend the enum to add new values (make your enum final to prevent it)
  • You can get a list of all the possible values (see below)

This Enum class is not intended to replace class constants, but only to be used when it makes sense.
