PHP enum
========

[](#php-enum)

Simple and fast implementation of enumerations

Introduction
------------

[](#introduction)

### Definition

[](#definition)

> In computer programming, an **enumerated type**(also called **enumeration** or **enum**) is a data type consisting of a set of named values called **elements**, members or enumerators of the type. — [Wikipedia](http://en.wikipedia.org/wiki/Enumerated_type)

### SplEnum

[](#splenum)

[SplEnum](http://php.net/manual/en/class.splenum.php) is not integrated to PHP, you have to install it separately:

`$ sudo pecl install SPL_Types`.

In addition, it's not a panacea:

```
class Month extends SplEnum {
    const JANUARY  = 1;
    const FEBRUARY = 2;
}

class Fruit extends SplEnum {
    const APPLE  = 1;
    const ORANGE = 2;
}

// you must create new instance before each use:
$jan   = new Month(Month::JANUARY);
$jan2  = new Month(Month::JANUARY);
$apple = new Fruit(Fruit::APPLE);

var_dump($jan === $jan2);          // false
var_dump($jan === Month::JANUARY); // false
var_dump($jan ==  Fruit::APPLE);   // true
```

### How to get enum with default value?

[](#how-to-get-enum-with-default-value)

```
final class Color extends ReflectionEnum implements EnumDefault
{
    const RED = 1;
    const GREEN = 2;
    const BLUE = 3;

    /**
     * @return Color
     */
    public static function byDefault()
    {
        return self::byValue(self::RED);
    }
}
```
