The [PHP](http://php.net "PHP: Hypertext Preprocessor") scripting language is missing one important data type: **The enumerated type.**

Today, with version 5.4 of the [PHP](http://php.net "PHP: Hypertext Preprocessor") scripting language, there is still no linguistic support for enumerated types. It only exists a Request For Comments (RFC) from [2010-05-21](http://wiki.php.net/rfc/enum "The PHP Group. PHP: rfc:enum [PHP Wiki]. 2001-2013.")) that suggests adding a enum language structure.

Many programming languages, e.g. Pascal, Modula-2, Modula-3, Ada, Haskell, C, C++ und C# have an enumerated type. Java, for example, implements the enumeration type via objects (see [Java Tutorial](http://docs.oracle.com/javase/tutorial/java/javaOO/enum.html "Oracle. The Java Tutorials: Enum Types. 1995, 2013.") and [Java API documentation](http://docs.oracle.com/javase/7/docs/api/java/lang/Enum.html "Oracle. Java Platform SE 7: Enum. 1993, 2013.")).

One can use the *`int` Enum* pattern to represent an enumerated type in [PHP](http://php.net "PHP: Hypertext Preprocessor"):
