PHP Enum Class
--------------

[](#php-enum-class)

> Enums are handy when a variable (especially a method parameter) can only take one out of a small set of possible values.

Konekt Enum is a lightweight abstract class that enables creation of PHP enums.

> **Why not PHP 8.1 Enums?** This package was created back in 2013, and has been in use across many libraries. We're planning to find the way to make this package be based on native PHP enums AND keep compatibility with earlier versions as much as possible. This is expected in the **v5.0** release of this package.

### Usage

[](#usage)

Extend the base class and define constants on it:

##### Example

[](#example)

```
class ChessPiece extends \Konekt\Enum\Enum {
    const KING   = 'king';
    const QUEEN  = 'queen';
    const ROOK   = 'rook';
    const BISHOP = 'bishop';
    const KNIGHT = 'knight';
    const PAWN   = 'pawn';
}

var $queen = new ChessPiece('queen');
```

Installation
------------
