Benefits
--------

[](#benefits)

- Type-hint: `function someAction(Action $action) {`
- No magick methods or phpdoc comments, only raw enum values
- List of all the possible values
- Own fields or methods in enums

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

[](#installation)

```
composer require palabs/php-enum

```

Create your first enum
----------------------

[](#create-your-first-enum)

```
use PaLabs\Enum\Enum;

class Action extends Enum
{
    public static Action $VIEW, $EDIT;
}
Action::init();
```

That's all!

Examples
--------

[](#examples)

```
function someAction(Action $action) {
   switch($action) {
       case Action::$VIEW:
           // some code
       break;
       case Action::$EDIT:
           // another code
       break;
       default:
           // ...
       break;
   }
}

$viewAction = Action::$VIEW;
if($viewAction->equals(ACTION::$EDIT)) {
// ...
}

$allActions = Action::values();
```

Custom fields in enum
---------------------

[](#custom-fields-in-enum)

```
use PaLabs\Enum\Enum;

class Planet extends Enum
{
   public static Planet
       $MERCURY,
       $VENUS,
       $EARTH,
       $MARS,
       $JUPITER,
       $SATURN,
       $URANUS,
       $NEPTUNE;

   private float $mass;   // in kilograms
   private float $radius; // in meters

   public function __construct(float $mass, float $radius) {
       $this->mass = $mass;
       $this->radius = $radius;
   }

   private const G = 6.67300E-11;

   public function surfaceGravity(): float {
       return self::G * $this->mass / ($this->radius * $this->radius);
   }
   public function surfaceWeight(float $otherMass): float {
       return $otherMass * $this->surfaceGravity();
   }

}

Planet::$MERCURY = new Planet(3.303e+23, 2.4397e6);
Planet::$VENUS = new Planet(4.869e+24, 6.0518e6);
Planet::$EARTH = new Planet(5.976e+24, 6.37814e6);
Planet::$MARS = new Planet(6.421e+23, 3.3972e6);
Planet::$JUPITER = new Planet(1.9e+27,   7.1492e7);
Planet::$SATURN = new Planet(5.688e+26, 6.0268e7);
Planet::$URANUS = new Planet(8.686e+25, 2.5559e7);
Planet::$NEPTUNE = new Planet(1.024e+26, 2.4746e7);
Planet::init();

$yourEarthWeight = 65.0;
$mass = $yourEarthWeight / Planet::$EARTH->surfaceGravity();
foreach (Planet::values() as $planet) {
   sprintf("Your weight on %s is %f%n", $planet->name(), $planet->surfaceWeight($mass));
}
```

Methods
-------

[](#methods)

- `name()` Returns name of the current enum instance (e.g. 'VIEW' for Action::$VIEW)
- `ordinal()` Returns ordinal number of enum instance in all enum instance start with 0. E.g. 0 for Action::$VIEW, 1 for Action::$EDIT
- `equals(Enum $other)` - Tests whether enum instances are equal or not

Static methods
