PHP 1 Line Enum is a standalone PHP class that allows the creation of enumerations in PHP. Every enumeration has its own class. Type hinting is supported. It can convert to and from strings. It supports bitwise operations and namespaces. It uses a simple syntax. It lets you get instances by name, by key, or by class constant.
EnumBitSet is a small project offering more functionality with enum types in Java. It is useful if you want to store a set of enums in a single database field. A toLong() method can be used it there are not more than 64 elements in the enum type, or toBigInteger() for enum types of any size.
